Conjure summon (necro) causes corpse drag aggro in velious.
 

I used conjure corpse to summon a corpse from velketors and the result was all the mobs gaining aggro as if I was dragging the corpse manually. I couldn't find anything that it should create an aggro chain. I could see this being an exploit for AE'ing + an annoyance if you have a legit reason to summon a corpse.

That certainly doesn't sound right.

Would have been some EPIC ToV trains to zone in.

might just be in velks. Did it from lord bob pull spot, and everything from where corpse on up ended up aggroing.

I checked the corpse drag aggro code. It does not trigger on spells. So I cannot see how it would happen.
