I personally believe that capital ships don't get enough glory. In the cinematic intro to Rebellion, almost all the ships are CS. But in-game, it's wasteful to use more than 6. So what I've done is remove the combat and support frigates and replace them with a frigate version of their respective CS.
TEC only for now:
Light(change?) to CSTransport
Heavy to CSBattleShip
Carrier to CSCarrier
LongRange to CSSiege
Utility0 to CSColony
Utility1 to CSSupport
I use a frigate type CS because the AI will build these in large numbers. It works beautifully. To the game its just a frigate, but it has all the stats of a CS.
Tech for removed frigates also removed.
Todo:
Cost balancing. (Cut price in half, credits metal and crystal, but it seems too cheap)
Apply to other races
Abilities balancing (Right now all their abilities are usable as soon as they are made)
Find a use for legit CS (Flagships maybe?)
Speed up combat (battles take to damn long)
Maybe add research requirement to some CS?
Balance remaining frigates/defences (they are so useless)
