However, I'll be the first one to admit that I'm having more fun in WoD than I had in Cataclysm/MoP.
Cataclysm made me quit within 3 months of its release, MoP didn't hold me longer either. This time around I do raid so there's that.
Dnno, this current game would be perfect if Ferals, Ret Paladins, Hunters, Windwalkers lost their respective interrupt effects, and replace them with different thing entirely. Ferals could potentially further increase mana cost on spells, Ret Paladin interrupt could be something like "if you successfully hit this spell on someone casting, you have free flash of light crit that multistrikes - it wouldn't fuck people over and stall the game but you'd be able to heal up the damage that you would've otherwise interrupted, Hunter interrupt should be turned into something else, dunno what - etc.
Also, dampening getting removed, in arena mana regen for healers being fucked up on purpose per individual basis and thus forced either into lasting 2-3 minutes when under full pressure from enemy team or last infinitely if you let them drink.
