Give us a daily Mulligan for ranked.
I think we've all had one of the following happen when we queued up for ranked:
a. Someone gets last pick, and threatens to feed, or in general throws a tantrum when they don't get middle/top. This usually results in someone either being forced to adapt a round champion into a square peg, after they announce "top or feed" after locking in with a top champion, or auto losing when two people are fighting over top lane. Or middle, or whatever lane the man child couldn't live without.
b. The guy that is clearly trolling, picks rammus with ghost and revive, makes no secret that he is going to build nothing but move speed items, might even admit that hes going to feed. Or the guy who picks Mordekaiser ADC, or any other thing that screams "Oh boy, a troll". At best, this is someone "trying something new", but without the etiquette to do it in normals or even better, a bot game.
c. Tons of bickering among the team before champion select is even over. Double points if it's the ADC and support yelling at each other.
These are just the ones that I can think of at the moment, but any of the above generally means you are going to lose the match. It's not even going to be close, or a remotely fair fight, you are just going to lose. So why are we forced to be a captive audience to what are basically super toxic players? They know we are captive, and unable to leave because it will get us a loss if we leave. So we are forced to either waste 30-40 minutes on the off chance the enemy team has more trolls than ours, or we eat a loss and a 30 minute (or longer) cooldown on rejoining a game.
Why would Riot not give us a daily(or even a charging mechanic similar to the reroll in ARAM, based on number of games played since the last one), that gives us at least the ability to avoid the worse of these outbursts?
