Well, Trader ID's got a loss of cargo maximum cap because people were all using them and not corporate ID's.
Same deal here. I say remove gunboats from them. It would make people perhaps join a real faction instead of loling around in their generic pirate gunboat that has no story on how they aqquired that Tridente and or Corsair GB, and let alone how they get away with intercepting/abusing Outcast ZoI...
