Anyways, I'm talking about this quest here:
Dr. Terrible's "Building a Better Flesh Giant" - Thottbot: World of Warcraft
Basically, you get to use a level 80 elite vehicle to kill waves of mobs. Its quite easy. And takes approximately 3 mins to complete. Anywho, if you let Dr. Terrible kill you after all the trash is dead, your rogue will drop to the floor. Vanish. The trash mobs will not despawn. Loot. Skin. Repeat.
I was getting about 8k Xp per 3 mins and 8 skins or so, as well as loot. Best part was its so easy I can watch TV and neglect the game.
Maybe this would be viable for an auto it program considering no movement other than looting is required.
