Well, battleships don't need a CD, they have battleship missiles. Not really good to prevent anyone from fleeing, but from cloaking as well as to get rid of the shields. I would suggest to replace the CD of battlecruisers and cruisers with something similar. A slow, heavy CD, not a "I-throw-battlecruisers-against-everything"-CDs. In other words: Getting rid of cruiser/bc CDs and give them Cruiser missiles for that slot that work like CDs. That together with slow battleship thrusters may be useful.
