Any chance you can apply a cooldown penalty to those who dodge games at the lobby stage. Had one guy do it three times last night in a row until he got a team he was happy to go with and another did it this morning - only going to get worse as folk start to protect their precious rank...
To my mind if you search for a game then thereafter you should have the same penalty for;
1. Not clicking Accept.
2. Leaving in the Lobby.
3. Leaving during the Game.
