In all my time playing league, there is only one complaint I have about the entire game:
It is way too easy to troll.
Regardless of the debated existence of "elo hell," people are constantly brought down the ladder by teammates who refuse to cooperate or just straight out don't try, I believe that there must be a better way to deal with these than to just take the hit to your elo and have forty minutes of your time wasted trying to carry yourself 4v5.
A solution my friends and I played around with in our heads is to have a system where you could start a vote against a player in champ select. For example if you have somebody who refuses to go support and says things like "haha nubs, i'm gonna troll." you could press a little red button next to their name, and a little red light would pop up next to their name. If two or three other players decide to press the button against the troll, the game would be disbanded at no penalty, and a copy of the champ-select chat would be sent to the tribunal. Of course everybody would be placed back at the top of the queue. People at the tribunal could then see the champion selections and the chat and decide for themselves whether the person was planning on trolling. If there was no trolling and the person was just trying to selfishly leave a game, then appropriate punishment could be handed out to whoever reported an innocent.
Not only would this save time by not sending people into pointless 4v5 matches, but it would also improve the overall quality and experience of League of Legends. I think this is a rather simple thing to put into the game, and I'm surprised that Riot hasn't already done something like this to compliment reporting at the end of the game. The tribunal is a great tool, and we should use it so that decent players dont have to waste 30 minutes waiting after dodging from a troll. I hope you guys like this idea! Please comment your thoughts.
tl;dr - ability to start a vote to disband game and report troll at champ select. Save time and elo.
