Okay, I don't know about other classes, I know it is supposed to be the same across the board, and I looked around and found that in 5.4, They were supposed to cap Vengeance at 30% of health in ten mans.
My question is, how accurate is this? Also, are there any bugs associated with this (Tool tip bugs specifically, I know on my demo warlock, it still tells me Fel Flame will generate 34,000 some odd Demonic Fury XD)
The reason I ask, is because when I tank Heroic Garrosh, I take every single one of his annihilate's to the face and come out of that phase with my tooltip for vengeance reading 700,000+
Fully buffed, I have like 1.1m health. So this is obviously more than 30% of my health for our ten man heroic group. I was thinking it might be a tool tip bug, but my damage on garrosh jumps up significantly after wards and my Frenzied Regen tooltip reads 1.1m+ for 60 rage.
So what's up with that? The Death Knight I tank with is like "oh yeah I'm vengeance capped after like 4 stacks." but unless I get to ten stacks or start taking Annihilates to the face, I never get that high and it seemingly has no cap, It's always going up, based on what tool tips say.
