As Vigilance spec I was noticing last night that if someone was afk and Overhead Slash had no cooldown I would have to hit that person 10 times (no crits, no misses, 1.2-1.45k per swing) to kill them assuming that person had 0 heals. Other than master strike it is the hardest hitting "instant" attack. If we weren't due for a serious fix the visual of someone jumping up and down with a light sabre 10 times in a row to kill an afk would have had me quitting the class if not the game.
