Team numbers not balancing correctly at game start

Yesterday I was in crossfire against a few people who were playing as a group. I've seen other threads complain of games not starting as it was waiting for players in the lobby even though there were 6 or more people in the lobby. In my case in one game there were 6 of us, the game was split 2vs4. I thought, perhaps I wasn't paying attention and it was 3vs4 with the 3rd man on on our team having left immediately as the teams were assigned... but then in the next match (as low and behold, that one did not last long) there were definitely only 6 of us were in the lobby. The game split 5vs1 with me being the 1.

I was amused by the futility more than anything else, but still. It is a demonstration that work still needs to be done in improving how the game sets up teams with parties in the lobby.
