Die Horseman, DieFollow

Ok, I have to admit that my poor warlock (my first toon actually) gets pretty dusty from time to time. Lately being little more than a darkmoon card factory, I started to feel like there was one particular thing I really wanted to do with him before Caty: Attumen. Daddy wants that horsie. But, there was a problem... I can't seem to successfully solo him on my lock.

I've easily solo'd this boss with several other toons (tanks are easiest, healer is longest) but cannot seem to figure out how to get a kill with my lock. So I have come to you, my fine fellow posters, for advice.

So far I've gone in as PvE Affliction, PvP Affliction (sorta SL/SL), and Demo (several variations). I've tried drain tanking, Feldemon and old Blueberry but nothing seems to work.

Aside from bribing my guildies or just giving up is there anyone with some suggestions? Anyone with a solo kill that might have insight?

Thanks in advance!

Sorry, I should have mentioned that I did check out many YouTube videos (where I found some great tricks for the trash) but I'm still having issues with Attumen himself. So I was hoping for some further tricks or techniques.

Off to try again! Thanks.
