A solution to dodging
I was recently inspired by this post :
Riot should add a Dodge button in queue. What it would do is Mark each player that pressed the button as Dodge and wait until the end of champ select then disband the lobby.
Reasoning: right now. When you've decided that a game is lost in champion select, the best method is not only to dodge, the but to troll as hard as possible in the lobby to try to get your teammates to dodge first. This creates so much unnecessary toxicity in champ select and sometimes even games that shouldn't if started yet
By waiting until the end, all players that clicked the dodge button would each be punished as a Dodge, the game would never start, and there would be no reason for the toxicity since you'd have no way of knowing if someone else dodged until the game would start.
