If you leave early, you don't get stats.

I agree with everything you wrote, except if they do implement this I Hope game stats will still count if your team mates don’t revive you and your banner is timed out so you leave the match. That’s not your fault, that’s your teams fault for not bothering to revive you so you shouldn’t really be punished for that. And I personally would hate to wait around and watch my team mates play if they didn’t bother to take my banner to a Respawn lol 😆
