On Third Floor of Amdapor Keep, when the Succubus throw their AoE's randomly when not even engaged across the floor, if your pet or party members are hit, even though you don't actually have said mob aggro'd, the pet will run all the way to the passive Succubus and will aggro all sorts of things along the way causing infuriating wipes. Before you can even realize the pet is missing and traveling across the map to the Succubus which is three packs away, you're dead.
