Citadel, Longshore, Assembly, Sandbox, are all dreadful excuses for maps. The only decent DLC maps were the remakes of old favourites, and even then the Midship one doesnt capture the Midship feel. Another problem is how often the DLC maps come up in playlists. Playing the Mythic playlist, I probably get Sandbox/longshore atleast 3 times as often as the others, and I've never, ever, come across orbital in matchmaking.
