Why is there no option to block a horrible player from ever getting to your team? You block him, he is never in your team again.
After a game is lost because of some very very bad player, be it toxic behaviour, or troller, or just outright newb who feeds 1-15 and doesn't care, you just wish you are never put with him in the same team again. Reporting doesn't really work, so you have no options.
We spend hours and hours, days, months, trying to win, and there's always someone who doesn't care and just destroys all your efforts. Why can't we just block such players?
Would it somehow destroy the matchmaking system?
This is the feature that would make us all happier.
