I spent 90 minutes in PoV today equipped with a parser and one rather vexed Razorfiend.

I kept the fiend slowed. I used no avoidance AC buffs. For mitigation AC I had a single V2. I altered my equipment, keeping AGI as constant as possible but boosting AC, and recorded the fiend's DPS on me for 20 minute periods. I didn't use any shielding AC (no AC on the offhand weapon).

I have all the mitigation and avoidance AAs available for the BST class.

Results:

My AC: 1004: DPS 54
My AC: 1101: DPS 48.6
My AC: 1199: DPS 48.4
My AC: 1273: DPS 48.2

So, it would appear that Beastlords (and I am guessing Druids and Monks by extension), have a soft AC cap in the 1100 region on Al'Kabor. Monks probably get more for their mitigation, but I believe the soft cap should be the same from what I've read on various PC forums devoted to this.

I would be interested to see what input other folks have on this - anybody wildly disagree?

If I've got this right, then I can stop prioritising loot and quests for AC gear, as I already have way more than I realistically need.

Okay, so ran another set of parses with a Monk and got different results. Monk soft cap is higher than 1100.

Haven't spent enough time with fiends to pin it down yet.

I spent more time with the fiends. This time I collected SIX times as much data as I did before.

For a beastlord, there is NO difference in DPS between 1100AC and 1200AC. The fiend concerned scored 132.2 DPS against me at 1100, and 132.4 at 1200, a difference so small that for the sample set I'd say meant the beastlord AC cap is definitely AT or below 1100 on Al'Kabor.

So, beasties, there is NO point getting an AC above 1100, on Al'Kabor at least we really are a DPS class. Rangers and Monks will both make considerably better off-tanks than us (except Monks don't hold aggro so well).

More to follow on other classes - this parsing is just as boring as you can get, so it will come slowly.

I find this kind of data very interesting and useful when trying to make a character better!

Statistical questions...

What sort of distribution models are you using (chi-squared, etc.)? What are your confidence levels, means, variations and the like?

Have you tried it against mobs with different atk. values?

I'm not applying statistical models as such, I don't have the expertise.

So I am simply measuring mean DPS over a 40-minute period from an unslowed mob - which seems to be the basis for most of the PC-side parses I've plagiarised ideas from. The data sets each comprise approx 3000+ samples. I'm not (presently), breaking the results down into mitigation and avoidance, although I plan to do that at some point.

Currently, I'm only using PoV Razorfiends. Once I've played with a couple of other key classes some more (Monk and Ranger), then I'll repeat the experiment in front of something tougher, though not sure what yet. Need a very high ATK but with no targeted or AE procs that will affect the results.

Kelorek`Dar has been suggested but I'm thinking something tougher like Diaku Armorer - so long as it just hits, doesn't ramp, doesn't flurry, and doesn't proc...

Hmmm.... Avatar of War maybe, if I can get a big enough number of healers to stand there and parse for 2 hours...

:D

Cool info TT. I like boring things. Can you link the program you are using for this?

Before applying the results of the PoV test, are you sure that it's the overall soft cap of AC for a BST on the server you are testing or the cap of AC that's effective vs. a certain mob (razorfiend in this case) of a specific level and ATK rating?

Historically, PoP mobs were designed to put an end to AC soft caps that were encountered for most Velious mobs. I'd be surprised if the cap for BST's for PoP was that low.

Like you mentioned, AoW would be ideal for comparison, but the "Elites" in tactics will probably give you a good answer as well. They are considerably higher in level and ATK compared to fiends so any differences should be picked up pretty quickly. I wouldn't use BoT "wing" giants or any or the common mobs in PoS since they can vary in level and many have an ATK rating similar to fiends.

This isn't the way that I see it. The softcap for us hasn't really changed much from when it was first put out (to replace the AC hardcap). Increases in AC are actually quite significant up to the soft cap. A 250 increase in displayed AC would show up as a large decrease in damage taken (along the lines of 25% to 30%). But, DPS dealt by mobs takes a lot of things into consideration. A mob's DPS ranges from a minimum damage to a maximum damage (these never change - aside from things like warrior discs and such). Actually damage dealt is present as a bell curve between these two end points - but the median value of the bell curve moves up or down depending on how your real AC interacts with the ATK of a mob. The median can never go above the max damage value, and can never go below the minimum damage value. Or, in other words, most of the time, if your AC is very high or very low relative to the mobs ATK you will take max or min damage.

However, for some mobs, the ATK relative to your AC maxes at some point. In Velious, for example, most mobs (except for bosses) are such that for a plate class, maximum effective AC is about 1100 or so. Any class whose softcap is at least 1100 - and who has that much AC (and this I think includes every class but the silk classes - as long as they have finished all the defensive AAs) will be just as effective as any plate class in tanking Velious most velious content. There are some few exceptions (most notably the Avatar of War). Apart from AC issues and defensive Disc, the other aspect of course is raw HPs. So for trash, my Cleric can tank anywher in Velious with no problems (and can heal himself to boot).

The original hardcap in Velious was changed to a softcap, and most classes get some return over that softcap. Now, defensive AAs (particularly the mitigation AAs) work effectively by modifying the softcap. They increase the softcap. For melee types, this is a bigger benefit earlier on, since they usually have better AC on their equipment. The casters won't see as huge a gain from this as they will from avoidance AAs - but once the casters get a sufficiently high AC, the mitigations help an amazing amount (remember that even silk classes will see a sizeable enough boost from mitigation AAs, that they will see a noticeable reduction in Damage taken).

With the softcap, several classes saw a huge gain in AC over the cap but most didn't. Eventually (as part of class balancing efforts and such) most classes got a bump in AC return after soft cap on the PC side. Our monks have something of a nerf caused by other issues. Monks originally had decent returns, and a high cap, which made them excellent tanks (of a sort) in high end Velious content. Back when I was doing Velious for the first time, our guild used monks as ramp tanks. They hadn't really gotten around to tweaking the ramp rate alot (its a proc) for most mobs, and monks had a high AC and a high evasion meaning that they were actually easier to heal as a ramp tank than warriors were. So monks were badly nerfed to change this (and eventually changed again but we missed the good modifications).

Most classes have a return above cap that makes it less than useless. For a Cleric, once we get past the eventual softcap of about 1450, we might see a real increase of AC of about 10 or 11 going from a displayed AC of 1450 to 2000. This exists on our server in part because at these softcaps (which are enhanced through AAs), it was only in elemental gear that characters saw the gains in AC which allowed them to get very high values (and thus created a need for correction).

At any rate, while PoP was supposed to correct some of these issues, what it actually does is raise the ATK on some mobs - and this goes up as you move through the content. Personal anecdotal experience suggests that the fiends in PoV level out pretty early. Cromis tanks there without much difficulty. Cromis solos in Tactics for example, but is limited to the normal ground floor ogre type mobs (the Diakus). Hendin's DPS spikes right up, and clearly Cromis's AC is nowhere near the where it needs to be for the ATK on such a mob - but our plate tanks with 1800 AC or so have no problems, suggesting (anecdotally) that there might be an effective cap for them in the 1800+ range.

So conclusion:

BST softcap is the same now as it was in Velious (and as a leather class will sit at around 150 worn AC - this is not very high).

BST softcap will go up significantly when mitigation AAs are purchased, but it will put a softcap at around 1100 AC (displayed AC - along with all of the other leather classes). Since this is likely below the effective cap caused by ATK on the fiends in PoV, the fiend parsing is going to be fairly accurate (while it might not be for a 2K AC geared SK). On the other hand, BST's make excellent split tanks for most Luclin and Velious era mobs.

At 1100 AC, with decent HPs, a BST can tank just fine at the fiends, but they do not make good split tanks further on up the PoP ladder, where well geared Rangers will tend to do better (higher soft cap) as emergency split tanks and plate classes even better.

Finally, getting more AC isn't bad, it's getting more AC at the expense of something else. The AC will be far more valuable for a BST up to the cap than just about anything else - but post cap, for a BST who wants to tank, HPs and the related attributes will take a more prominent role. You won't want to drop below your cap to get them, but you will look more at upgrades that give better resists, HPs, and attributes than at the AC on the item. Velious gear had a lot of high AC, while Luclin had less AC and more stats and resists. PoP tends to do all of it.

Cromis just stated more elaborately what I was saying: PoP mobs were designed to end the issues of an AC cap in EQ. THis was done mainly by adjusting their ATK above that of the dismally low velious and to some extent, luclin mobs. Getting more AC is Velious era was kind of demoralising once you realised it didn't make a lick of difference against 90% of the stuff you were tanking, especially if that AC gear didn't have good stats on it. Better off wearing some uber caster gear.

In any case, my point for TT is: Your soft cap is 1100 for mobs like PoV fiends, but not for PoP as a whole. IN those cases where a raid plan starts going to poopoo and you have to step up and tank, that AC over and above 1100 will serve you well.

Would BoT Militis work well as a target for future parsings?

I don't think the basic Torden yardtrash would be any good Placer - I can tank those for XP just as easily as I can stand in front of a Razorfiend.

But some of the tougher ones - say, once you get inside the towers. The minis would be good if it weren't for the fact that they proc extra DPS through effects, which would sort of ruin the results.

The problem here is not to think of mobs that hit HARD (because that is a factor of their maximum and minimum damage values), but mobs that have a high ATK. In fact, I

You could easily have a mob with a minimum hit of 500, and a max hit of 1100, and an ATK of just 1000. It would do MORE damage than a mob with ATK 2000 that had, say, a minimum damage of 105 and a max damage of 487 (PoV Razorfiend) - BUT, it wouldn't be so useful for finding armour cap values.

Shissar Elites may make pretty good subjects, and they're always eager to hit on me, or maybe Rhag`Mozdezh (as he doesn't proc anything apart from an AE DoT that would show up in a separate section of the parser).

If Destiny had 6 good healers with nothing better to do for a couple of hours, we could even try Rhag`Zadune, but he's pretty ferocious...

Actually Stamm, the softcap isn't based on the ATK of the mob. There is in fact a real softcap - which has a set value based on raw AC of worn gear. Above that softcap there is a diminished return.

However, for some content, there is no return beyond the softcap because of the ATK of the mobs. So, if the fiends do not show a return (of any sort) on AC over 1100, then the ATK of the fiends has capped the AC at 1100 (apart from any other issues). And a good choice might be to try the same parsing against mobs in HoHA, where we would see higher ATK than in PoV.
Quote:
The pre-PoP patch did a few things:

- The cap on item AC was no longer used except at lower levels (twinking was a concern since that was before recommended level items were in heavy use).
- Shield AC was added to the class-based cap to give shields more viability
- Class AC caps were changed. Monks were lowered the most, but beastlords were lowered to the same level as druids (yes, they were nerfed too). Cleric and shaman caps were raised above druids. The caps generally followed the armor archetypes of plate/chain/leather/cloth.
- All classes were given returns on AC over the cap, not just melee classes. All casters and priests received the least, followed by the melee classes. Rogues got the same return as monks, as did berserkers when the class was added. Beastlords and rangers got slightly more, followed by bards, then knights, then warriors.
Beastlords should get about a 17% return on AC over the softcap.
