Protoss carriers petition

At the very end of a game when there are no minerals left, the carriers are rendered useless they have intercepters which cost 15 minerals each. Meanwhile other units for Terran such as the anti-air Turret do not require any minerals, nor do the Zerg such as the Brood Lord. There should be an equalizing element such as another method of attack for the Protoss Carrier. Please consider this suggestion. Thank you to Blizzard for such a great game.
