This bug is very hard for SE to fix since they need to fix the mechanics that would adjust more than just Ampador Keep since they probabaly use a set of rules for different mob mechanics etc that would in turn affect other areas. (its very common to do this because its much easier to change if the code is the same).
If SE does fix it, its not going to be right away, and probably not for a long time actually. People used to train in Haukke and SE changed dungeon mobs to never leash, and that implementation stayed in 1.0 with Ampador keep. That WAS their fix for this behavior soooo i don't know if they really know of anyway to stop it even.
