Why the surrender timer should be lowered down to atleast 15 minutes, Maybe 10.

You know when you queue up for a game, Go through champ select normally, Go through loading screen then get in game, That is when one of your teammates runs down your lane, Runs into the turret and feeds a kill, And he continues to feed for the rest of the game, Why should me and the rest of my team sit here watching our troll intentionally feeding for 20 minutes, Even if its not somebody feeding and its just someone trolling around the map or is AFK, It doesn't take us 20 minutes to realize that 1 of our teammates is intentionally feeding/trolling/AFK, I've talked about this idea with multiple players in game and they agree. Now i understand Riot may not want games to be settled so early on, But with a troll/feeder/AFK it already is (Only sometimes with an AFK though). There is nothing left to say other then that its obnoxious to wait 20 minutes for the chance to end the game there, And that reducing the surrender timer down to 15 minutes would fix this problem.

EDIT: After a bit of thinking i'd kinda say 10 minutes probably isn't a good idea, But i can't change to title so oh well :P
