I WANT A RE-DO

My last game was complete and utter (excuse my language) bullshit! I was in my series and this game was going to determine whether I get promoted or not. My jungler was afk, bot fed, seriously, like Sona ended the game 1/16. Plus to top it all off, Kayle afk'd and just sat in base. I need a re-do. I really wanted to promote, I did good in my lane as well. But oh well, you really need to do something about afks, not just banning them, but something in the gameplay where if you get an afk, your team gets a percentage boost to balance out the incoming damage and the damage output.
