I know I can't be the only person who can't find a group to beat the incursion on challenging. My gear score is 203, I have a high dps & health but my electronics is at 20k. I have beat the regular incursion many times and also made it to wave 14 with a group on challenging but I forgot to add them. My GT on xb1 is iChasstin. Yes I have a headset.
