From wowhead updated talent calculator. Im not 100% sure this is confirmed or anything: Emancipate is now 15% base mana (1% less then cleanse). Hammer of wrath now proc mastery <== my guess is they want to make sanctified wrath more competitive with holy avenger, currently Sanctified wrath was the worse of the 3 talent, alot of it had to do with the fact that HoW was only stronger then judgement in our rotation, because cs had mastery and exo hit harder. Now with that change HoW might be our strongest hitting non 3 holy power finisher. At least in theory.
Now shield of the righteouss for prot will stack a self buff(bastion of glory) 5 times increasing self healing by up to 50% on wog (on top of the buff to increased black change by 10% and block ammount for 30% for 6 second. Mastery now increase the block chance and the power of bastion of glory.
Selfless healer now need to stack 3 times. But in addition to reducing cast time by 100% and healing on others by 100%. The mana cost is also reduced by 100%. Sounds like a decent trade off, looks like Emancipate will be our only mana usage now.
Also supplication now changed to fol being a 100% crit, no more 300% 300k fol crit on my brother while questing.
