Burst is going to be high when characters just hit max level but haven't upped their resilience yet. We don't think burst is a problem in PvP right now. We do think the Ret "rotation" is problematic. You essentially have a spec without a meaningful resource (Rets generally don't run out of mana) with attacks that are entirely cooldown-controlled, which allows them to be front-loaded. The bubble is certainly powerful along with dispels and things
like Freedom.

Ret talk
More talk about wanting to change ret paladin basic rotations. I also suspect they're looking at Blessing of Freedom for nerfage.
