Mythic bosses have too much health

My team focused down a Mythic Knight for over 10 seconds and couldn’t kill him. 8 people, all with either power weapons or vehicles, couldn’t kill a single enemy in ~10 seconds. It’s stupid.

ummm… its a mythic boss… ofc u won’t kill it in 10 seconds

It’s the hardest level boss you will face and you want it to die in 10 seconds?
