How about instead of shutting down 2 arenas and booting everyone, shut down the arena with the lowest number of players. This way 2/3rds of the players can continue their current quest, whether it be a long bomber run, or a good GV fight, a nice furball, ect.

The way it is now, some people get their buff runs disrupted, or we simply lose a good furball, whatever the case may be. It then takes quite a while to start up another decent GV/air battle, and some people lose perks if they dont make it home to land in time for the "boot"
