May 1st 2009 1:20PM My guild was doing Naxx a couple of weeks ago and we managed to wipe on a boss.
Since some people are terribly slow at corpse running, we usually start messing about while we wait.
Personally, I drank a noggenfogger elixir, and then cast mirror image so there were 4 skeletons.
The mirror images ran into the boss' chambers (even though it was over 50 yards away) and started attacking the boss.
Since that day I remove mirror image from my action bars the moment I step into any instance.
