Warrior- Not really viable at all, dk can do everything they can but better, prots eh right now as well
Hunter- Only bm is viable, MM actually requires skill and is enjoyable but gets stomped on by BM
Rshammy- Inferior to all other healing specs
Feral-Forced to fc now instead of having a choice
Ret pally- Dk's taken instead for same reason as warrior
On top of that nerfs incoming for Boomy's and Shadowpriests with their static damage reduction being removed and bm hunters will be slightly more responsible for their damage output making it harder to avoid their burst.
