Ret will soon scale with spell damage by same amount, so when someone hits the Ret Pally in PvP they can not going to like it
.
The only things that need to be fleshed out is the mana return from Ret (60% of damage caused gives mana) and if one of the 3 group member is always that Ret Paladin. This is outstanding for solo play though.
I am happy Holy Shock is getting buffed and there is a neat AoE heal with a Pally flavor, but they cost a lot of mana. In raids you will be doing Hand of Sanc for SA, but how about 5-mans?
The new trees are great, the new talents enforce that Prot uses Warrior tanking gear and Ret still uses Warrior dps gear. The only problem is they seem too good and they will likely be nerfed
