I know FD seems reluctant to borrow good ideas from EVE (system security ratings being the most obvious answer to griefing), but honestly, I would love to get kill / salvage missions to large structures both in space and on the surface. This seems like a no-brainer and the assets are already there. ED seems meant for flying a small ship "Descent" style through a wrecked station popping rogue skimmers and scooping loot crates. Everyone enjoys a good dungeon raid now an then.
