I was just sitting in a WG where the enemy had no shot of winning with like 5-7 minutes left. There were no bases being held, there’s just no possible way to win. I think with time factored in that it would take to capture the bases and get vehicles to the wall, destroy them etc, it’s just not possible.
It would be nice if the game recognized where it’s just no longer possible to win, and the match would end. Can’t imagine this would be very hard to figure out with the numbers on Blizzard’s end.
