I know this wont be a problem for many People, seeing Necro at around 1.4% playrate for DH. Nevertheless:
When a Demon from the Demon Hunter Necrolord Covenant Ability “Fodder to the Flame” spawns in Perdition Hold, it instantly puts me in combat with all “Mawsworn Valuators” in a very large radius. I get the aggro, not the demon. Those “Mawsworn Valuators” trigger all enemy NPCs they come across on their way to my character. Makes this Area literally unplayable for this Class x Covenant Combination, since you cant even avoid to use it, as it is a passive procc.
I sincerely hope this is a bug, as questing in Perdition Hold becomes extremely dangerous this way.
