No way on druids. Their DPS is still very lacking behind mages, rogues, even now hunters and warlocks in PvE. And they are still a joke in PvP.
DW Shaman will be able to put out fury warrior DPS if geared correctly; but I find it will be VERY difficult for them to reach that level of gear, and if they do, it will require a lot of leather armor, making them much softer. Aggro will also be a huge issue, thus forcing them to stay below rogue damage.
Elemental Shamans will still be the strongest and most versatile imo. An elemental shaman can still heal if needed; a enchancement shaman really can't.
Priests are becoming VERY strong in PvP if geared correctly.
Hunter off-specs are becoming more viable...not necessary good, but viable.
Warriors, rogues, paladins...not much will change. I still don't see much paladin tanking going on. Druid tanking become stronger skill wise, but the itemization is still an issue, although there is still time to fix it.
Mages...meh...fire will reinforce itself as the strongest spec. Ice and Arcane are cute, but too weak to be viable as a lead DPS.
Warlocks....lol. It's going to become World of Warlockcraft if they don't do something there...insane DPS buffs, insane aggro reduction buffs, and at least one VERY strong PvP skill added in each tree?
