I have edited ZoOoOoM's profile just a bit to suit me a little better. Since I'm not even friendly with Argent Dawn, the repair/vendor served me no purpose other than to screw me up, so I cut it. In stead of using the 3 hotspots in the original profile I've re-spotted it with 10 in order to really get down in the "branches" of the scar. This should grab every single mob inside.
I dropped my pull range down to 40, because I was running into the walls often just like brabbit mentioned. I think this was due to targeting a mob a little outside of your pull range on the other side of the hill/wall, and when the bot tries to move him a bit closer to reach your actual pull ability's range he just runs against the wall until the mob patrols back into range/whatever.
I'm actually thinking about creating a profile right here beside the Pestilent Scar (around the Noxious Glade) in order to farm up enough rep with Argent Dawn to become friendly and open up the repair/vendor. Would anyone be interested?
As a side note, this is my first little venture into profiling (or editing), so don't be too surprised if anything is wonky.
EDIT: I guess Karma appreciated that I shared the edited profile, because about 30 mobs in to my run (and about 5 oozing bags) after posting the profile I got my first Disgusting Oozeling. Yay!
