Dear Blizzard:

Thank you ever so much for not fixing pathing.

I tried to solo him at first as a level 41 Shadow Priest (I was just leveling a lock. I got cocky). After OOMing and running away, I looked him up, and read something about him pathing around a wagon.

BRILLIANT.

I found said wagon, hit him with Shadow Word: Pain and Devouring Plague.

And proceeded to skip merrily over the wagon while watching him run around it and sloooowly die.

Got stuck a few times and had to fear him, but besides that, it went off without a hitch.

Here's a screeny of right after I killed him, I didnt think to do it while I was killing him =/

EDIT: Here's the jumping spot for any class that can dot him. You can try with direct damage, but he is rather speedy =P
