So Blizzard are considering. (Read all the blue ghostcrawler posts but to lazy to find them)
-Righteous Vegeance DOTs to stack upto 5 times.
-11 prot talent PVP ability (Can't be too strong cause Holy will have access to it too)
-Maybe adding a secondary effect to Crusader Strike (Don't expect a mortal strike or anything)
-Bubble and Avengin Wrath to have 30 sec shared cooldown
-Drains/Manaburn drain a pecentage of your mana so it doesn't matter if you're a ret paladin or a priest with 15k mana.
I actually really like what's going to happen if they fix us up like this with more PVP viable abilities. Ret currently was a skilless braindead spec that killed stuff before they could even use up all their cooldowns. Taking away ridiculous burst and giving some PVP viable utility was the way to go about it in the first place.
If promises hold true, I think we'll finally have that necessary arena utility..
