its 5.5k , 2 gusts because EF, 2 gusts from bonedust proc, w/ addition healing from bonedust on each gust (which is like around ~7K ea, which you didn’t even include in the math anywhere), + revival + bonedusted revival
Gust of Mists = 5.5K
Essence Font = 5.5K × 2 = 11K
Resplendent Mists conduit = 30% chance to make Gust of Mists proc for 100% more healing
(5.5K × 2)~2 = 16.5-22K
+Crit
((5.5K × 2)~2)~2 = 27.5-44K
on Bonedust Brew = (5.5K × 2)2 + (7 × 2) = 36K
w/ resplendent ((5.5K × 2)~2)2 + (7 × 2) = 47-58K
+Crit
(((5.5K × 2)~2)~2)2 + (7 × 2) = 69-102K
+revival 10K
= ~46K (or ~56K if revival bonedusts) , per target before any resplendent or crit procs (which are very likely across a raid of 20 people getting hit 2x ea(+revival hit that can crit))
mastery/vers necro has the most powerful version of revival, bar none.
i’m not saying you should run it, venthyr is definitely the better option in keys/raid with crit/vers;
i think the point of all this math is to say that maybe revival isn’t underpowered, especially when attempting to compare w/ other healing raid cds, its actually extraordinarily over-the-top, you’re just running a build that is more focused on other things than having an over-the-top raid cd. (you get a worse revival but also get fallen order)
====================================================================
also, just for fun, math for your crit/vers:
Gust of Mists = 1.6K
Essence Font = 1.6K × 2 = 3.2K
Resplendent Mists conduit = 30% chance to make Gust of Mists proc for 100% more healing
(1.6K × 2)~2 = 4.8-6.4K
+Crit
(1.6K × 2)~2)~2 = 9.6-12.8K
on Bonedust Brew = (1.6K × 2)2 + (7 × 2) = 20.4K
w/ resplendent ((1.6K ×2)~2)2 + (7 × 2) = 23.6-26.8K
+Crit
(((1.6K × 2)~2)~2)2 + (7 × 2) = 33.2-39.6K
+revival 7.9K
= 28.3K (or ~36.2K if revival bonedusts) , per target before any resplendent or crit procs
accounting for max crits = ~42.6K ( or ~58.4 if crit revival bonedusts)
So basically, at your absolute maximum rng, you can achieve the base healing that revival will provide to mastery/vers. If revival crits for mastery/vers, eons ahead. If any thing crits or gets even a single resplendent proc, eons ahead. The exponential value of mastery, specifically when talking about Revival, far outweighs crit.
