I think that the ghosts weren't highlighted enough. For me, it's the little things that make the difference between good and great (With Destiny, though, that would be between amazing and jaw dropping.) I think you should be able to get solid color shells from the Guardian Outfitter, Crucible and Iron Banner shells, and special faction shells from Dead Orbit, New Monarchy, and Future War Cult. Eye and Light color would also be great additions as well. I would love to be able to make a ghost look like a Exo guardian.
