The real time ranking system I think is the root of a lot of this. It allows people to know where they stand and they can look to the community on how to improve their game.
Instead why not organize a catch-all chat for people to talk, like a Discord. Let people talk off-topic and organize to play games and such as a class if they want.
I think that's a great point but one that the Rocket League community somehow solves.
Trying to make education more like Rocket League, ignoring the wildly divergent motivations of the people involved, is a fool's errand.
What are the objective differences between getting better at Rocket League and getting better at stats?
Agreed if we don't understand or create a basic framework, trying to put lipstick on a pig and making stats look like Rocket League is dumb.
