The DP nerf was reverted indeed but the following nerfs remain;
Flash Heal, Renew, Binding Heal and Prayer of Mending - All these spells heals for alot less
Glyph Mind Spike - only works from Mind Spike that aren't instant casts from Surge of Darkness and therefore removing a large portion of burst
Dispersion - now belongs to the Shadow school, meaning it can get locked out.
Phantasm - Removing the "untargetable" part of it
Halo - It no longer hits stealthed enemies
Divine Star - The area of effect has been nerfed a significant amount
Those are all the nerfs i can rememer on the spot right now but i bet there are more coming.
Some nerfs are acceptable and logical and some arent. Thats not the discussion tho.
Comparing to mages and locks i can safely say that spriests are the most nerfed caster at the moment.
