I have a LOT of level 100's in EQ2 and have done all the recent level 100 content, except I didn't buy the brewery instance.

I tried tons of different group makeups. The best I found is:

SK as the tank
Dirge
Coercer (Ill/Coercer is required for a group in most of the new content)
Warden
Mystic
(Ranger/Brigand/Assassin) as DPS - take your pick
