Melee get an expansion, casters get 24 hours?

Title says it all. Casters (not just mages) are a bit over the top right now. My main issue is how fast blizzard responds to QQ from the community about it and acts immediately, when the whole WOTLK expansion casters have been complaining about melee.

Check every arena season blue and tell me that melee doesn't own this expansion. So you give casters 24 hours of OP and the world ends. Here comes the nerf bats. Fine. Its needed, I agree, but stop with the double standards. You ignored melee for the whole expansion and let them feast on clothies for well over a year. Keep it fair blue, because as of late, it has been anything but.
