I feel there is a problem with the fleet upkeep system. Once you research to increase your fleet size, you can never lower your upkeep. I think that at each descrete level of ships there should be a separate upkeep amount. If you get in a battle and lose all your ships it doesnt make any sense for you to be paying an upkeep. It not only makes sense but will help people recover when they lose battles. I dont know if I posted this in the right section, but hopefully this can be included in the next patch.
