If you jump without your crew on board, right now you just have to pay the revive cost. I’m not sure if it would be preferable, but as far as realistic gameplay goes it feels a little funny that you can completely abandon your crew on a rock and jump away and they’ll teleport right back on board.
Additionally, you don’t have to worry about revive costs for jumping to the hanger/ending the mission, so crews could realistically just have someone stay on the ship as a pilot ready to jump the moment things get a little too hot while everyone stays behind farming as much as they can with zero consequence to having abandoned your crew.
I’m not sure if it would make sense to have it so you’re physically not allowed to jump until everyone’s on board, or just have the penalty be something different, but I just find it interesting that as long as one person makes it out with the ship a the end of the day it makes no difference as to who was on board.
