Game start connection check

Please add a connection check 30 seconds or so after loading game and if someone is not connected, cancel the game and count as loss for person that did not connect. 5 out of my last 6 games had someone that either didn't connect, or didn't connect until 5~10 minutes into the game, it would be pretty easy to do a connection check at 30 seconds into game, by then everyone should easily be connected and if someone isn't just count it as a dodge and cancel the game. It is really infuriating to play game after game of 4v5, and it could easily be prevented with a simple connection check.
