I'm no slouch. I know I'm capable of this achievement. I've done Three Lights on 25M when it was current and have every ICC 10M achievement with my current guild but heroic LK. I'm looking for a group of people that have done this fight to down it quickly and easily before Cataclysm hits. If that doesn't work out, I'll take individuals, but I'm hungry for this achievement and this mount.
I would also be interested in a heroic LK kill for about 15K, but not until I get this taken care of.
