There should at least be a penalty for leaving before 15 minutes.
Too many people leave before 5-10 minute mark where it doesn't really make much of a difference.
I understand that in 4v4 if you haven't held a single fuel point for a full 15 minutes then its probably over but if someone leaves 3 minutes in just because they lost an engagement then they need to be punished for that. One leaver in 4v4 ruins the game for the other 7 people.
why, i dont want to waste my time on a game I know is lost, and tbh I have little sympathy with people who have 8000 games in random but still haven't gained a basic understanding of the game. It's a different story when I'm matched with actual beginners.
