It’s true that this comp was only good because of chaos brand and AI.
A tank spec having 7 aoe stops by itself? Not important to the meta. 2 dps with massive overtuned aoe burst damage profiles and a million defensives? Psh, nothing meta worthy. A force multiplier with a group wide cheat death and 5 aoe stops as well? Why would that help?
Blizz dug deep, and is putting an end to the culprit with these nerfs.
