I was just in a game where the team decided to surrender within the first two minutes. Why? I don’t know. I voted against it but others agreed. Maybe because we didn’t push hard enough? We still had full health and the enemies were nowhere near our sentry.
I feel that the surrender option should only be available after 10 minutes, also, a penalty for surrendering should be that the opposing team gains the majority of the XP earned by the surrendering team as a punishment for not seeing it all the way through.
