Pathing - Overthere
 

It looks like there is no pathing in the overthere, as mobs go right through the walls in the halls of the skyfire zone entrance instead of pathing up the stairs and around corners

I believe this was true of all non-dungeon outdoor zones on Live.

While it makes sense there was no pathing in the outdoors areas, I dont remember mobs just running through the walls near the skyfire zone out and it being accepted, perhaps there was no pathing for the outdoors areas but when it came to going to the indoor parts of outdoor areas i believe they would path and not go through the walls
