There seems to be a lot of bugs and inconsistencies with mob aggro this season.
Fade for priests, a spell that prevents you from having any aggro at all, doesn’t function half the time. While doing ?? Kyveza, there were times she’d stick on me instead of going on Bran or one of my pets. Similar issues transpired in normal delves where mobs clearly tagged by my AOE Void Tendril stayed on me the whole time.
This isn’t exclusive to priest too because on my druid, the “Force of Nature” spells is supposed to summon adds that taunt and aggro all mobs yet it is no longer doing so.
For clarification, the spells do work as they should occasionally, but there’s frequent moments where they’re not preventing aggro on the player.
