The problem with space stations is that they're just that - stationary. All any WarShip has to do is move to Extreme Range and start lobbing shots with capital weapons. Since stations, per the rules, can't mount capital weapons (except naval missile launchers), it won't have many Extreme Range options to shoot back with. (The TRO:3057 BattleSat with a Naval Laser was retconned into oblivion once the line developers realized that introducing something that could be mass produced and reliably smoke DropShips meant that their core game - focusing on giant robots being dropped from orbit to fight on the ground - would be ended by such a development. Ditto for the video game standard of mobile surface-to-orbit naval weapon batteries.)
It can launch its fighter compliment, but odds are they won't have anywhere to park in short order. There's a reason why the Bastion-class station, once so common that every major world had a pair, was down to a dozen or so operational examples by 3025 - they would have been popped like pimples by WarShip attacks in the First and Second Succession Wars.
A Bastion might make raiders with only AeroSpace assets get nervous, but once a WarShip enters the fray, the space station becomes nothing more than a juicy target for the gunnery crews.
