I cannot count how many games I've lost or seen the other team lose because they lost someone who quit or disconnected. I really hate it when it happens to me so I can sympathize with others. I think Riot should make a system where the team that loses because of quitters or a disconnected player should have a loss forgiven instead of just a loss, so it doesn't hurt their score. This is especially important in ranked games I think because of the affect to a player's elo. I've had plenty of trolls and just plain baddies in ranked games who ruin the team by disconnecting, being afk, and quitting. I do not know if Riot has the capacity to do this system, but I'd like to see them try.
