Doesn't count as a nerf if it never went to Live server. We are after all beta testing.
Remember the 0.4% power is per rank, so at rank 3, it will be restoring 1.2% AND this is groupwide. Hmm I did not check to see if this crits too.
---> Went on test, Divine Mana is procing about 601 power on me... power pool of almost exactly 50k, so that comes out to be exactly 1.2% power per proc, so no it does NOT crit for power.
Also tested the new Wrath of Divinity. To get the incremental damage, you have to cast the debuffs. Once they increment wears off after 30 seconds, you have to recast the debuffs to get the increments again. This includes having to recast Divine Fate of Healing again, which resets the 10% mob health drop heal on it. Booo. But I guess we are having to choose more dps or more healing at that point.
On an epic training dummy in heal spec, 2:23 min fight, total dps parse was 43.7k, Wrath of Divinity was 3.3k dps for 4th place on the dps parse, with crushing, Divine Smite, and Divine Strike beating it. Divinity Punishment did only 367 dps but average hit is 26k damage, almost exactly what Wrath hits for. Keep in mind that epic dummies don't hit back, so it takes forever for your reactives to wear off and proc the Divinity Punishment, so it would probably parse higher in real fights with MT eating up your reactives. Oveall this is looking like some decent dps output.
