I don’t think you’re right about 4v4 at all. By any measure. However, I have long thought about how there should be a 10v10 casual though. I agree that that would be a cool idea and it would enable the people who just want to fart around to be separate from the sweaty players, which is a complaint i hear often.
Idk about the gpu screen recorder but for the keychain for Discord if you disable the KDE wallet subsystem (which is just in the kde system settings) it should stop asking. it’s never caused me an issue and made the discord popup go away. its a dirty solution but its what worked for me.
