In Vanilla pallys were just the raid healers of the alliance (if you look at tier)... in BC pallys could tank and heal while wearing the same gear.... in WOLK gear became more spec dependent (no more tanks with x amount of spell power gear) in Cataclysm, WTF. Holy Power! Pet/Guardian things?! I cant tell if they're becoming even more OP or blizz is just saying "screw it, they're OP enough, might as well make them the unofficial hero class of Cataclysm". I made a pally in BC and leveled it all the way to 80 and i have to admit they are extremely on the OP side. So please, if you agree or disagree, let me hear it.
