3v3, great! Except when its: 2 AI and 1 human VS. 3 humans.
2v2, I'll take it! Except when its: 1 AI 1 human VS. 2 humans.
I've had a 2 VS. 2 with 2 AI's (from the start) VS. 2 humans.
It seems the human paired with an AI or 2 is almost assured a loss while the human team a hollow win. These game situations happen more than not.
