Opt out of a Game

I'm so sick and tired of people being total assholes in champ select. I was going to play yasuo and our top laner bans him and starts talking shit about how I can't play yasuo and i've never even met this guy or did anything to agitate him. Earlier our adc banned my friends pick and called him shit. Riot should have a system set up for opting out of games. It's unfair that I have to sit in a game with an asshole teammate that hates me for no reason and playing a champion I don't want to play. Like set up a report system in the lobby so if someone wants to be a dick and ban their teammates champions, they can be reported and you can leave without a penalty. But also if they are reported falsely then just punish the guy who reported falsely for leaving.

Also maybe if people weren't giant dicks to each other for no reason they might actually be decent at this game. Most of the people that I see do this feed their ass off crying about how shit their teammates are when they solo lose their own lanes.
