So two things that have bothered me for a while with how the mobs are acting.
First, sometimes mobs will randomly reset. If you're kiting an elite for a while, i'm sure you've encountered this. They will just randomly reset, go to full hp, and run back to where they were before you pulled them.
Here's a video showing what i'm talking about.

Second, sometimes mobs cant get to you and evade bug, but they don't reset. For example, in instances if you are on a location that a mob can't reach you what they should do is evade bug for 5-10 seconds and then reset back to where they originally were. On here, however they just stay there and remain evade bugging so long that they cannot path to you.
I don't have a video for this, but I can make one if need be. It's very easy to replicate.
Didn't really know where to post this, so i'm posting it here.
