As in, you run a tribute run. You collect your buffs. You reset and repeat. Now you have 2x buffs. Technically you could have others clear it for you and summon you around, enabling you to get up to 32 DMT buffs (assuming you have no enchants, as these STILL count toward your buffcap). Effectively, this would be 115%*32 more health or 200 * 32 more melee attackpower. Or 3% * 32 more spellcrit chance (capped at 99% though).
Fengus’ Ferocity,Mol’dar’s Moxie,Rallying Cry of the Dragonslayer, Slip’kik’s Savvy and Spirit of Zandalar these buffs will no longer work on targets over level 63.
Not fix for stacking, but I’m sure that it stacked before 2.1 and was abused in TBC raid.
I find that hard to believe, simply because of how hard and tight encounters in TK and SSC were. Particularly pre-nerf.
All of those encounters would be trivialized by multiple +15% hp buffs. Hell, mages or warlocks would be able to facetank the silly-looking stalkerdudes they were kiting on Vashj.
Besides. Even if that was how it was, it does not have to be that way now. In my opinion it shouldn’t. Imagine how quickly we’re going to be blazing through future content if we get the green light for stacking multiple DMT buffs. World first 20 min BWL hype?
