First off, I haven't been able to duplicate this more then twice, so I'm not 100% sure what causes it. One day when pulling a mob, i got a 4 mob train and I used /warp loc and miss typed my numbers so it threw me into a wall, the mobs all followed to the wall where I was at and could not hit me. Durning this time my pet picked them off 1 by 1 and the mobs didn't hit me or my pet even once. About 50 attempts later, I finally got it to work again, I warped into the wall by changing all 3 sets of numbers by 15 and I was able to kill a mob again without me or my pet getting hit. Again I am not sure of the limitations or what else effects this, but it is definitely something to look into when you have more free time.
Cliff Notes:
1) Preset a waypoint in a wall
2) Pull mobs
3) Prepare to fade or succor if it doesn't work
4) Profit if it does work!
On a side note, I parked my alt near my mage, and noticed that on the times it did work, my mage would fade from site into the wall, all other times, it would appear as if my mage was just standing there.
