TOFS in TOV sucked cause of the ice in the center room on floor 1, moving around there was a pain if you didnt have a pet class to try and pet pull.
PoI is pretty awful for pulling PL trains, I've avoided that zone because of that reason.
MG last night I pulled a blob in the metal slime room from the top of the ramp and he warped to the second or third floor and brought friends that proceeded to warp on me.
Dulak back in the day you could strafe near a spot by the entrance and force mobs to run back and forth, was a good headshot spot back before vinelash.
I forget exactly where it was, I think it was lost gnomes instance but I used to run the barrier of the wall and my train of drachnids would warp behind me so it was pretty easy to gather them all up.
I seem to remember a similar warping bug in luclin where if i could sick my pet on something, it aggroed and if I sat against a wall the mob would warp to me and avoid multi pulls... this was back in the day when pets didn't have their own aggroe like today.
