PSA: There's no need to quit a co-op game against AI just because one of your teammates drops at the start

I’ve had this happen more than once now. One player drops at the start, and the rest quit, leaving me to 1v4 the AI. I still won, so we would have won even more easily 3v4. I’ve played with several other teammates in the past who have stayed in, and we’ve won 2v3 or 2v4. So if anyone who plays co-op reads this and quits in this way, please don’t do it, you can still win if down 1 or more players, and the team is more likely to win if you carry on playing.
