Surrendering/getting booted from a team game gets you 0 points
Pretty straightforward. It's kinda BS when your teammate surrenders or gets booted but you still win the game, then they get the points as if nothing happened. If you surrender, you shouldn't get any credit for your teammates' hard work when you put them at a disadvantage and they had to plowextra hard to win without you.
The OP is absolutely right about this. Surrendered/booted teammates share my hard-earned victories way more often than they should. In particular, I just won a 2v2v2v2v2v2 game where my joy of knocking out five other teams was diminished upon finding the points I earned were split with my "teammate" who got booted in the first round!!
As things are now, players can collect free points by joining every team game posted with no intent of playing and allow themselves to get booted with the realization that some teams will still manage to win without their help. The points should be divided amongst only the remaining and eliminated players of the victorious team. Surrendered and booted players don't deserve to share the spoils of victory.
