We should not be seeing any Bounty Hunters flying Liberty cap ships nor should there be non-faction members purchasing such vessels. In order to fly a Liberty Battleship ... you'd need to be friendly enough to actually have a Liberty IFF.
Independent lawfuls should be flying Civilian type vessels.
Pirates and unlawfuls should have their own equivalent vessels.
Junkers should have a variety of junked capships. We already have the recycled Rheinland Pirate Cruiser (which needs a name change ... should rename it to "Junker Cruiser" with a description explaining how they recycled it from wreckage). Would be nice to see a junked Liberty Gunboat, junked Rheinland Battleship, etc ... each of these ships would be like the original but with nerfed armor and power capabilities ... say 75% armor and power from what the original vessels have.
Zoners typically come across advanced tech stuff anyway. But their vessels should not be considered available to civilian. Civilian vessels should only be purchasable from corporate bases.
