I am not usually one to complain about frost mages, but they don't seem to have endured any significant nerfs, either. Sure, they've been scaled back, but like warriors, the nerfs are a rather minor concern. Why warlocks lost a damage on the move spell that is hardly game-breaking, is beyond me. I suppose it's driven by similar balancing concerns as those behind making PoM/Poly no longer work, when PoM is arcane only.
According to some people we should just 'deal with it', though.
