Ok for ranged after three resets i figure out the place you need to stand and put your ranged toons. Below is a pic so as to make it easy for you to know where to set up. Remember lots of agro from the tank. When he casts first mirror image stop tanks dps heal wait then taunt and attack, Bring your tank to where mine is. Then you can dps the heck out of him. Hope the SS helps out.
