You know, it wouldn't be that hard to get a practical idea of what would be appropriate. What if Temerity and Destiny did a joint VT raid? Those mobs are quite appropriate targets for testing DPS. Everyone who comes turns on their own logs so we each can get our own data. That should be pretty accurate.
I think it would be cool if we had different people of the same classes agree to different strategies. Maybe we'd kill two mobs -- one where everyone of a particular class used the same strat (this will help to "normalize" the data to make up for differences in gear). The blob 2s would be perfect choices for that.
We could do two sets of parses, too. If when someone goes OOM he announces it, then it's easy to get numbers until OOM plus overall.
Use a Destiny tank as representative of agro holding. (The top-geared Tems tank can probably hold better agro than the top-geared Destiny tank, which is probably inappropriate for a VT mob parse.) If we've killed a few other mobs together, everyone should by then have a pretty good idea what they can do and not pull agro. Anyone who gets summoned loses -25 DPS from their score
