No class for me, really, I'd say I don't have much reason to complain. Some classes will be tough, but seeing as it looks like we can probably still beat anything...
The only thing that's been punching me in the face is the elemental shamans' talent that makes them recieve -30% damage when stunned (or feared or silenced). That's plainly badass, it becomes 30% as hard to CC+take down an ele shaman.
