Warrior: Slight nerf. Either slightly tone down mobility or the 75% MS
Paladin: Retribution: Tone Down burst and slightly increase DPS. No, I don't have the foggiest idea how to do that
Paladin: Holy: No idea at all, haven't seen many lately
Paladin: Prot: Nerf the shit out of it.
Death knight: Is fine, but change CoI and DG without nerfing.
Hunter: hm, tough one. Nerf damage (especially kill shot ffs) and slightly buff passive survivability
Shaman: Elemental: Fine.
Shaman: Enhancer: Getting fixed
Shaman: Restoration: Another tough one. I'd say reverse the ghost wolf changes and instead buff survivability
Druid: Balance: Getting fixed
Druid: Feral: Too much burst, instant cyclone is unnecessary
Druid: Restoration: Too powerful vs. one dps, too weak versus being trained by 2
Rogue: Balance is fine, but broken as hell.
Mage: Fine
Lock: Fine
Priest: Disc is fine, buff shadow
