EVERY CLASS CAN KILL ME! EVERY CLASS IS OP!
^^^ This is what I've been hearing all over everything about wow lately... Granted, I don't know ANYTHING about 85 pvp from Cata, it still sounds about the same to me. But I do hear mages are severely OP.
Remember Burning Crusade, with all the demons and junk, Warlocks = severely OP at first. Wrath with all the undead, Palys and DKs super OP at first. Cataclysm, elementals.... Which class do you expect to be all OP and junk at first? Mages, and what should be Shamans... are Shamans OP in cata? o_O
