There has always been talk of how transports are really only meant to get to their destination and not much else, especially in terms of combat. Freighters have already been seriously buffed in terms of potential already so I do not know how this idea will go down.
I had a very random thought this morning, the idea of a razor or torpedo turret to fit into the class 2 slots. But yeah you will be like "ooooo you so stupid, fighters use class two turrets tooooooo" well true, but not all freighters are blessed with a massive amount of class 2 turrets, the Anki for instance only has 1. ANYWAYS what do we do to stop fighters from abusing the idea of a turreted razor? Make the power consumption much much higher than any VHF's powerplant! Freighters already have triple fighter powerplants anyways... and freighters are not really combat ships in the first place, so maybe freighters should be that one kind of trader who pirates should be afraid to attack... they can already outspam most fighters, and mount pretty crazy shields, and they are alot smaller than most other ships so I doubt this idea will be well received...
