The only thing blizzard could do for me is actually attempt to make content challenging after the first month of raiding. After you get to a decent item level this game is basically a kids game where "everybody wins". The only thing about wow that has ever been hard is hardcore raiding where they attempt a boss 100+ times until they get the proper RNG to kill a boss before everyone else. Woohoo.
That and the fact that pvp is probably in the worst state it's ever been where they're just throwing out random additions into live and calling it balance.
I don't understand why people care about being competitive in a game that isn't designed for competitive people.
