This was very helpful. For future seekers of help: ignore axe ironman's aoes, go for archers, then knuckledancers, then firedancers as they appear. Use single target attacks, and try not to provoke aggro on anything you aren't killing immediately. Stand still when the mech puts the glowy purple floating circles on you to avoid getting thrown in the air. Do aoe on the insect looking magitek things that appear in the third wave. Then single target the leftovers to kill them quickly. Kill axe guy if you see he has low health (your chakra attacks will do incidental damage). Then focus on big mech last, all the npcs will be helping now.
