Any chance at chopping back the energy requirements for the mortar series of torpedo-turrets? Not too far mind you, it's still a good idea to keep them restricted... but a gunship can't even fire the light mortar once. The light mortar is about 2 sunslayers worth of damage, and probably won't be mounted on any battleship (especially when medium mortar has the same energy cost O_o)... so how about knocking that drain down to ~100k on the light mortar so gunboats have something to play with?
