SolA: Eye Pulling Mage Mobs Doesn't Engage their Pets
 

Using an Eye of Zomm to agro the Gnome Mages, their pets don't successfully transfer agro when the eye dies. So the mage is attacking the eye owner, but the pet will just stand there. Once the Mage gets hit, the pet will join in. But Makes tanking a few of these mobs at once easier, since their pets aren't involved.

interesting. similar behavior when you attack a mob while the mob is summoning its pet--pet wont aggro until additional aggro occurs on the mob.
