In 2v2 why does one base end the game?

[Sichas]

I've thought the same thing but come to the same conclusions as the other responders to this thread. However, my GOODNESS have I had some Witt-challenged teammates. It's been painful. I had one guy spawn camp me with his snipers. That was cool. Another guy would let me kill the opponent capping a Witt space and then jump in and take it though I had none. Needless to say, 2s annoy me right now, with the exception of a random partner I found and have since been ranked with.
