Stop players from dodging when auto-filled.
Those players who dodge every time they get auto-filled... It isn't right that some of us should dodge our auto-filled roles while the rest of us just play.
When someone dodges from an auto-filled role, next time they entre queue, they are guaranteed that auto-filled role. Also, don't tell the public that you have done this. That way, those dodgers will continue to get the same role(support let's say) over and over and over, every time they dodge.
