It would be so much fun to have spaceships in the Crucible. It could be added like Sparrow Racing was added. Guardians could customize and upgrade their spaceships with navigation, weapon systems, propulsion, shields, and colors. It could be 6v6 with goals such as defending space beacons (a, b, c) like defending zones in Control or relics in Salvage. Guardians could have pilot armor like racing armor.
Elite Dangerous for Xbox one and PC is all about spaceship combat. It also has a CQC close combat play mode.
