I have been playing this game for a while and I really like to try out mods... But one thing that bother me is how most mods involving ships did not adjust their availiability (ie rarety). This result in markets and fleet composition to be flooded with modded ships (often the crappy ones) and the vanilla roster to be really hard to come by. Heck, when you have multiple ship mods installed, sometimes it can be really hard to find a ship you like, be it vanilla or not. Also, since 0.96a, no nations has access to all the generic BPs like low tech, midline and high tech, many mods did not bother to specify which vanilla faction has access to what so many of the modded ships are just availaible through blueprints or arms dealers...
