Using BBs and CAs as bombers doing an SBR sounds pretty cool. I guess they would be impervious to interceptors though ? Maybe tacs could intercept ships only ?
Think it’s just a matter of finding the right numbers for your fortresses piscolar. You’ll just have to playtest it out. My concern would be that they’re not too powerful so they can’t be cracked. I like the idea of having a ground unit present to activate them.
