"Judgement of Wisdom: mana gained reduced to 1% of maximum mana and proc frequency cut by 50%. This ability was flat out better than Vampiric Touch when the mana provided between the two really needs to be close in order for the decision between Shadow priest and Retribution paladin to be a real one."

"Judgement and Seals: Damage reduced by 20%. This is the major damage adjustment -- a lot of damage was coming from these. We do realize this hurts Holy and Protection as well, and that is something for which we are prepared to offer compensation (particularly if it hurts Protection's threat generation)."

These are part of a list of changes to nerf Ret damage.

That second one being the major one but as stated hopefully they get it settled for tanks.
