From Blizzcon '08 (transcription posted by Anauel on Elitist Jerks):
"Concern about ret pallies doing burst damage." Applause. "However with that said I've raided as a ret paladin. Are you guys going to tone down burst damage in PvP for ret paladins and keep good damage in raids? We've been waiting for a long time to become raid viable and don't want to loose that." GC: "Lots of bugs in beta that made [ret paladins] do more DPS... we don't think [current damage] is way off, honestly." GC: "Don't nerf me bro!" (Tons of laughter). Chilton: "We've tried to take it away from the uncontrollable proc damage...we want them to feel strong...we want to put a kill in the hands of a player [,not luck]."
So, sounds like everything may well be fine, at least until we get some proper Arena PvP at 80.
