2 vs 1 co-op

Hey there, I thought of this, and I really think it's a cool idea. We all know the concept of a 2 vs 2 Co-Op game, right? Well what if you want to test your skills, like REALLY test them, and you want to go 1 vs 2? We can't do that since you Need 4 players. We should be able to :3
I've done is many time with my real-life friends, but it's a hassle. I have to open 2 accounts, put them both in, invite my friends, and make my one account leave after I start the game.
This may not make too much sense, so here it is in a nutshell: Implement a 2 vs 1 co-op, please. Thanks.
