Ranked champion select needs to start banning players

I've been in 3 games straight where everyone did their bans, picked their champions then someone dropped right before game start. This needs to result in a ban to stop these people from wasting anyone elses time. Because what they're doing is dropping when they don't like enemy team player line up and it's not ok. select can take 5-10 mins and im sick of it. It's been 6-8 games straights I can't get into now, someone always drops.
