They should also make facial and other bodily apearances much more customizable. Like you said, it's just so pointless seeing all the profile pictures of your teamates as well as the characters lined up at the end of the game if they are pretty much identical. Having unique characters could actually help players stand out from one another etc but as long as you are limited to just a few facial presets, that will never be the case.
I also feel that there should be some full space suits because, obviously, these captains are fighting in the vacum of space and they should be equipped properly in case the hull is breached. It just seems inapropriate for someone to go into a deadly space combat zone wearing an outfit with exposed skin and that doesn't look tactical / combat ready.
Of course there are more pressing matters for the devs to focus on but they should get to this and fix it at some point.
