Bards get a lot better in PoP
Beastlord dps increases a lot due to AAs and new nukes
Necro DPS takes a jump in GoD due to dot crit AAs, but they are good in PoP
Wizzies are gonna stay good for burst DPS
Monks, Rogues, and Rangers kinda just maintain the status quo
Mages should improve DPS a lot bc there won't be any mitigation of the mighty buffs nerfing their pets
Wars are going to be the best for taking hits for a long time, but Pally or SK will probably be the preferred group tanks due to their snap aggro
