NPC range pathing

Ommamar

So I noticed the change in the AI where it is very common for NPCs who use range attack to try to back out of a fight to attack from range, which makes sense and is a good step. The problem is particularly noticeable in delves where they have a tendency to back all the way down the common T staircase at which point they will either aggro all the groups below or reset then come back with full health. It is good you are trying to make pve combat more dynamic but please fix this issue as soon as possible.

I've noticed this and a tendency to back away behind walls and other obstacles, or down cliffs or off platforms. There have been a couple of times when I've ended up completely losing a mob because of this (as in: the mob backed off somewhere, I lost track of it while fighting other mobs, and it never came back).

So I'd agree with @Ommamar on this: having them back away out of combat is a good thing (when you're fighting 3 ranged mobs and they all back away in different directions it makes you actually have to think about the combat instead of just spamming an AoE), but improving the pathing would make it much better.
