I certainly would not design a large battleship with hundreds of crew that would be exploded by snub craft. A battleship solaris gun uses enough power to operate 27 vengence lasers, I would just make room for those tiny things on my battleship instead... what is more deadly, 1 BS solaris or 27 VHF fighter guns?
Yeah but balance. Things do have to be complementary to one another and work from a game design perspective. Battleships can't kill everything I guess...well they can kill everything, they are just not good at it. I do think battleship VS battleship fights should last longer though
