I'm in (RL permitting).
Either Lower Guk or Splitpaw seem like they would be fine targets. I think we might want to see what sort of force we can muster and then make a final call. Lower Guk seems like it's a bit more dangerous, and it would probably be good to have several rezzers available. I've been to Splitpaw many times (though not often too deep) and it's managable with a good group, so I'd say we'd be safe with just about any raid-size lvl 35ish force.
Another option for a dungeon-crawl style raid is Kaesora. It has a very nice XP bonus, lots of nice class drops (a CLR shield I've been drooling after, spirit tomes for casters, some decent robes, daggers, swords, etc), and it's very doable for anywhere from a group to a small raid at this level. With a raid I think we could do some camping for loot and also clear the dungeon to the big baddie all in one evening.
I can't think of any single-target type areas at this level. I'm open to that type of raid if that's what we go with, but at this level, to get the most loot and XP for everyone, a dungeon crawls would probably be the way to go, I think. Though I could be wrong. Not a lot of raid experience here.
Anyway, that's just my $.02
