Same old, same old... Say, how many times this has been brought up again? I've lost my count already I think.
I currently use my battleship as I've got tired being constantly chased on light fighter, as if every larger ship have unstoppable urge to smash my little blue craft. Not to mention I like challenges, and certainly this ship provides them due to it's sheer size. And when outnumbered I run out because this ship is too valuable to loose (I play D2-like semi-hardcore mode). I would have chosen gunboat and I had it at some point but that blue one is somewhat broken when it comes to balance. Cruiser has broken hitbox, so it leaves me out with two ships to pilot: the light fighter or the battleship.
There I made suggestion in a similar thread in mod development section about implementing of idea of death penalty for battleships. Hopefully it will find it's way into the mod and thus make people to be more careful about their precious battleships.
Increasing prices, battleship licensees will do very little to solve the problem.
