My Personal Feedback.

Missions:
Co-op missions are really lacking right now, the replay at the end most of the time just shows you nothing if a different player finished the final objective,
also maybe make the missions not instantly end when completed, it ends up being rather frustrating getting your current attempt interrupted because you are playing with someone better than you.
Bearing missions should be rings, it is really frustrating to barely miss a Bearing because I just missed its invisible hitbox.

Always online:

The option to at least hide other players would be nice, i dont really interact with other players and they are usually just more of a hinderance than an addition, not to mention it would be nice for performance.
