I am still of the opinion that just removing armors in general will improve matters. Even without any other changes (with the possible exception of turret steer for Gunboats).
It means the guns we have wont' need a massive rebalance unless we decide to do something special to make Light Fighters more useful. Possibly increasing hull damage on most guns, thus making dodging and shields the "main" protection for ships instead of armors.

ANOTHER IDEA: For capships, I've had an interesting thought; instead of nerfing Turret Steer, why not simply remove the thrusters on Gunboats and Cruisers, and add a replacement device which, when active, causes them to turn and strafe much faster for a short period of time. Including for Battleships.
Granted, the versions on Gunboats and Cruisers would be far more efficient/faster then Battleships, but a battleship dodge just might make manuver warfare between caps more interesting.
