Hello, imo you pretty much have to have w,a,s,d on Do-Not-Pass. If not they will run opposite directions when you right click and move your angle with your mouse. I haven't ran 2 mages yet, thinking im going to soon, but from what i have read around here, you need to just have one of them be the tank while the other just pew pews behind him.

Edit: And for the loot function, i am also still looking for a way. There is that multiboxer v2 addon out that will auto accept quests and follow after combat, but i still haven't found anything to loot like you're talking about.
