I have been playing on the ptr and holy crap, priest are the best arena class in the game now. Don't have to worry about dieing anymore. Self penace will heal u back up full in under a couple sec, get the penace glyph for shorter cd, and you dieing can't be a problem. Now that priest won't die what else makes us OP? Shadowfiend!!! hits for 1k each hit and crits for 2k, you can burst as much as a mage or rogue if you pop shadowfiend and holyfire and penace. Your health is now increased. So you won't die and you burst like crazy, priest owners are going to be very very happy.
