Being a soloist I badly want multicrew with NPC and winging up with NPC.
I believe we will get these features eventually.
It will probably take a lot of patience though.
Larger ships should get minimum crew requirements just like in Frontier Elite 2.
But acquiring crew should not be as difficult

.
I still remember that I got stuck for a while after I bought my Panther Clipper, because I could not find sufficient crew via the bulletin board.
Winging up with NPC should also make escort missions possible I believe. It would open up cool new gameplay.
