I dont know about you guys, but my guild has been stuck on phase 4 of Mimiron for the last week. Try as we may our efforts are thwarted. When messing around like i do best, I found that you can actually apply Baby Spiceto the lower body of the Machine in P4 and make the Head attackable by melee. This can help greatly with keeping everything within the 15 second kill range. I havent been able to take screen shots but its a pretty easy concept to understand.

Thanks , hope it helps you out.
