Arena/Fleet Battle Timeout solution

I think the idea has been proposed before, and a lot of players have brought up the same issue each time: if what you suggest gets implemented in TW/GAC, all you have to do is go in, take out even just a single enemy toon, maybe do a bit of damage, and just let the battle time out. Which may not seem too bad for when you yourself are going on offense, but the same change would also benefit your opponent(s). Try to imagine what would happen then in GAC, and especially in the guild-event that is TW.
