As lordsteve said in the other response , each T 6 ship comes with a unique trait after maxing out mastery level on that ship . Traits are usable on ALL ships , so a lot of people probably buy ships just for the traits and then discharge them . Admiralty cards once you unlock that . Once you unlock a ship get to the initial screen where you can change the ship nameregistry number the ship will add a card for use in the Admiralty system . If you didn ' t know , Admiralty is basically if your ships were Duty Officers . You send them on missions and they return with substantial rewards . Every ship has a unique card , and each card has a bonus , such as ignoring event modifiers , multiplying critical chance , etc . Collecting is another thing yes , but I personally haven ' t met a pure collector in the game , but I ' m sure they exist . Ship speeds are something you don ' t really worry about in space , as most of your speed is determined by your Impulse Drive and Warp Core . Ships do not provide EC , Dilithium , Zen , Lobi , Reputation Marks , Fleet Marks , etc . Some ships like the Ferengi ships come with an Exchange console , and I think someone told me one of them had a Dabo table , but I can ' t personally confirm that . However , those were lockbox ships . Overall , I can ' t think of a good reason to buy anything from the store .
