"Divine Aegis Critical heals create a protective shield on the target, absorbing 50% of the amount healed. Lasts 15 sec. Priest - Discipline Spec."
Sounds like PoH no longer contributes at all to DA if it doesn't crit
"Rapture Removes the cooldown on Power Word: Shield and reduces its mana cost by 50%. In addition, when your Power Word: Shield is completely absorbed or dispelled you are instantly energized with mana equal to 100% of your Spirit (excluding short-duration Spirit bonuses). This effect can only occur once every 12 sec. Priest - Discipline Spec."
So PW shield is 50% cheaper, but nerfing rapture to 50% of what it previously was.
EDIT to fix a big correction here - The DA nerf is big, but I was expecting something more from penance is not even there (though its still ptr, so expect a buff to it).
IMO, I think DA needed a nerf from PoH as well as rapture toned down a bit, but the DA change seems like they it was done in knee-jerk fashion. But its still the PTR and again since they havn't even gone through with the penance change, lots can happen.
Ah and there is a solace change there too, but it seems more relevant to shadow.
Just to clarify - the rapture nerf in the end won't be felt that huge since the cost of PW: shield dropped as well. The cutoffpoint right now is 9150 spirit. if you sit above this number, you will be slightly nerfed. if you sit below, this change going through will be a buff.
But the DA change is a straight up nerf.
