Blizzard needs to spend less time balancing and more time bringing out more content for it's large, bored userbase. The fact that Blizzard is wasting it's time address important issues like "Fury scaled a little too well" or "Rogue's have .32939543 too few DPS in a PvP environment" is why the official forums are getting bloated with posts about how bored the players are. It really doesn't matter. The classes are balanced to the point no one is going to take all Fury warriors. It's just natural that some classes are better than others. All that matters is that they are fun, not balanced.
