Corvettes in gravity wells only
The corvettes as currently configured are more like a modern Fast Attack Craft than a real sea going corvette. FACs are limited to coastal areas since they are not large enough for ocean travel. If they are to be like FACs then they should be limited to operation in a gravity well only. Another problem I have had with fighters and bombers is that they never need to be rearmed or refueled. Its like watching an old western movie where the six-shooter never runs out of bullets, it unrealistic. They need to go back to their ship/hanger for a set amount of time before they come back for combat.
