Queue times & Dodging in team games

I enjoy playing 4v4 a lot, but recently it takes about 30 Minutes so get into a ranked game.

Queue times are not that great but the main issue seems to be people dodging a map they do not want to play. So waiting 5-10min each time adds up quickly.

Maybe discourage people from dodging would be a quick solution? Something like you can not queue up another ranked game for an hour or something. Or redesign the whole queue so you could ban more maps?
