Remove Battleships, Battlecruisers, Carriers from the pirate factions. It is odd to see douzens OC/Corsair/Hessian and etc. BSs when most of these factions are low on resources, food and any other goods.
It is absolutely rediculos to enter a battle with 20 caps on both sides and only 1-2 fighters/bombers flying around helpless. Make capships for the 5 houses limited or more expensive. The same for the pirate factions(for the Cuisers and Destroyers).
On the other hand increase the hull of the caps and reduce their maneuverability.
