"Why help someone get better when you'll never see them again?"
A statement brought up in a discussion about how to comment on other player's constructively, rather than just insulting them. It's a pretty easy mindset to get into, but it got me thinking. What if the chances of you seeing a random player you were just in a game with weren't always slim to none? What if the system intentionally grouped you with previous teammates when possible, so that you played with people whom you had more practice cooperating with?
With complete anonymity, people have a tendency to want to play team games by themselves. These people you just met aren't your teammates, they're just random players whom you share a goal with. There is very little improvement a person can do in a single game, so in the mind of many players, you're always better off improving yourself rather than other players who you'll never see again. The problem with that mindset though is that if everyone thinks the way, the "random" person you are grouped with who does poorly, isn't really understanding what they are doing wrong with whatever it is they are failing.
Of course the biggest concern with a system like this is people worrying over getting tormented by the same toxic player over and over again, and yeah, this will definitely happen. However, you can always report them multiple times, and they will know that. (just don't be obtuse about it and rub it in their faces)
Just think about how friendly league was when it was a brand new game with just a small community (at one point even lacking match-making), where you probably knew most of the people you played with already. Think about how differently you act when you are playing with your friends who are less skilled than you, as opposed to how you act when some random guy is going 0-6 and the enemy he fed is stomping your team. The problem isn't that the game is full of jerks, it's just that when we're helpful, we don't even know if they're actually taking our advice and it certainly doesn't help our next game we play.
