Kikatsu , why should fighters carry torpedoes at all ?
Fighter have guns and missiles and mines. bomber have pods torpedos and heavy guns. It makes classes of ship more different and that is good thing.
Torpedoes dates back from Vanilla freelancer when there was not bomber ships so fighter acted as all in one. We have mini razor , that is more than enough variety of staff fighter can mount.
What are torpedos for ? For bigger targets. Fighter is not meant to attack cruisers and GB. But with buffed missiles and guns and mines and minirazor they can attack transports if they like bigger fishes and can give some support in greater engegement to deal some damage to bigger ships if needed.
