Why isn't all the intended adjustments going live right now?
PvP atm is horrible, it's really enjoyable to test your new abilities and your opponents new moves, then you meet a full retri team and they faceroll you to death.
I don't blame the retris, deny a child candy for a couple of months and then plonk down a 5kg+ bag of their favorites in front of their noses... though I'd wish they at least had some grace, crying like children "I'm canceling my account!" "Sign this petition, save retri!" and other rubbish, If any other class/spec got an IWIN button (bubble + JoJ + hammerstun + "flying hammer of 3k+ crits") you wouldn't be crying if Blizzard corrected it.
