Have noticed this a few times now, my guild master noticed the same thing (we’re both Mages, unsure if that matters).
I pull a social mob like a gnoll, we’ll call it mob A. Another player, not grouped with me, pulls a different gnoll, we’ll call it mob B. The other player either dies or runs away to the point that mob B should reset, except instead of resetting it comes charging at me, while it’s still tagged to the other player (so I can’t poly it).
This has happened very often, and even in the event the other player doesn’t die or run away from the mobs, I will still be locked in combat until they kill all their mobs.
I have tested this numerous times. It’s the same on Kobolds in Elwynn Forest, Gnolls in The Wetlands, Orcs in Redridge, Gnolls in Redridge, Defias in Westfall, and Twilight Hammer Cultists in Darkshore.
I make sure that I am not AoEing, I do not buff or cast anything on either the other players or their mobs, I don’t even use a potion on myself or buff myself, and it always still happens the exact same way.
There’s a Warlock in my guild who doesn’t believe they’ve encountered the same thing, they think it must be a Mage thing for some reason.
Is this a bug? Is this working as intended? I know it’s been a long time, but I don’t remember ever running into social mobs and aggro working this way.
Edit: I just tested it further by waiting for a druid to start fighting some raptors. I proximity aggro’d two other raptors, ran them past the druid, and out-distanced the mobs so they reset. Rather than them attacking the druid, they ran back to where they started just like they should.
This does seem to be a Mage issue.
