Our first Anub'Arak Heroic kill was possibly one of the ugliest kills in the history of WoW. It seriously looked we were going to wipe with 2500 health left... then Elija, who was the last man standing, saved the day by popping his bubble long enough for him and dots to kill the boss.
For those who want to experience the mingled joy and shame vicariously, Apol (a.k.a. Òrion) has uploaded a video.
