So you go into a game and there's a guy who says "enjoy the negative elo, I'm feeding" and picks revive tele twitch. A guy dodges. Then you try to click that little red X at the top but you can't because it lags that one second it takes for them to remake the queue and you're paired with this guy again, causing a chain of dodges which you can do nothing about until you dodge during champ select and lose elo.
I would suggest that people actually be given a chance to leave games in which others are intentionally trying to make them lose. How about each time the queue is remade, for the next 10 seconds, you can leave queue without losing elo/ getting a 5 minute penalty, even if the game has been made?
Another, better option would be to completely remove requeue. This has the added bonus of making sure that afkers do not get put back into the queue system.
