A few times in my recent naxx runs mirror image has been pulling aggro. I'm not casting them right away. I usually wait till I pop my CD's so I have the reduced threat. A couple times now when I cast it during a boss fight, the images pull aggro immediatly. This caused a wipe last time it happened, but I didn't have much of an explanation for the raid, considering I had been useing them all night with no trouble. Is this happening to anyone else? Known bug?
