Troll Report
My idea is to add a report button during the champion select phase of a ranked game. The report would say something like, "Report for trolling". How this would work would be if three players report the same player for "trolling", then if someone dodges they are not penalized with the wait timer. If all four of the other team members report for trolling, the game exits champion select and the player reported for trolling is put on a wait timer. Trolling defined as a player trying to take a lane already spoken for, bringing a champion to a position where it is not at all meant to be, etc.
My inspiration for this idea came from a ranked game where the first pick asked for lane preferences and someone said ahri main, he then banned ahri. After that, (since we were the second team to pick, two picks at once), the summoner below him ended up picking nasus after a long wait, called top, and locked in. Several seconds later, the first pick chose irelia, locked in, and also called top. When it came time for me to pick a champion, I didn't. And as the timer approached zero, one of my teammates thanked me. Everyone knew he was trolling. ...And then I went through the low priority queue timer.
This report button never has to send any information for devs or moderators to deal with. If three of the players agree that someone is trolling, (more than possible for a duo queue), it will not have someone that dodges to have a queue wait timer. Also, 3/4 of the non-trolling team = 75%. The number of people that reported the troll would not be shown, meaning, they still have the risk if they leave. But if Everyone else agrees and reports the same person, then the game should exit and put punish the reported. If you have read all of this, thank you for your time and please consider it.
