Crewships: They shouldn't be taking so little damage per shot, much less boarding shouldn't be almost required. I say almost since you can use abilities and missiles, but they don't work well enough unless you spam them all on a single Crewship. Make attacking from the outside viable, reduce armor or health or increase Railjack damage perhaps? They're good as tanks and I like the idea of that challenge, but they're way too good at their job.
Archwings: In short? Make them tankier. Even on the first Earth Proxima mission they can't take more than three shots before dying. Alternatively, make the projectiles slower and not so pinpoint tracking so we can at least dodge them.
Resource Gathering: I don't usually have trouble with exploring maps but it can be very difficult to see resources dropped from fighters. With the vast expanse of the maps combined with dogfights you can easily lose things that may be useful to you. At least add a waypoint on dropped avionics, turrets, and components if not all drops. Collection range is good.
