Well done. I'm curious though about spreading out your toons with the back to the wall. Was this something you started doing after several wipes or did you do it from the start (since you say in your vid that it took quite some attempts). It seems the smartest thing to do to take out the orbs. No orbs can come from the behind and everyone faces it all the time.

On a sidenote, besides one for the challenge this is about the only fight i'd never multibox unless you have a mixed team like you.
