I played with this once before, and I confused repeater some how. I think it was because I had the "send next click" to my warlock only so he can summon an infernal. While that same key was for the mages mirror image. But its probably better if you have the aoe hotkey on a key that doesn't do anything on the others who don't need to use the aoe button. Just my speculation, didn't do a troubleshoot session on it.
