LeaverBuster Needs to be reworked

I understand the purpose of preventing people from leaving games or just dropping because they are being toxic or are teamed with a toxic player. However, it often seems that the toxic players become evident during champion select (such as people who auto-lock their champion and avoid the typical role "discussion"). There needs to be an option for leaving a queue or dropping during champion select where players don't get punished. The game has not yet started and they are avoiding what would essentially be a ruinous game for everyone by preventing gameplay with a clearly stubborn and uncooperative teammate. I'm not sure what the work-around could be, but there simply needs to be a way that players can avoid getting into a match with these kinds of players without suffering a penalty for wanting to enjoy their gameplay.
