People would get better at the game (or quit queuing for randoms) if we were allowed to roast them for being bad. Unfortunately, we are now at a point where politely worded constructive feedback, even when phrased as a request rather than a demand or whatever else "sets people off" these days, is an actionable offense.

So, simply put: need to revert the TOS. Allow the shaming of people that are incredibly bad at the game, and we will see a decrease in the number of those people tainting the queues with their presence.
