Can someone explain the stars in Mission Archives?
I think they represent how well your team is doing, but do they affect experience received? That's really the only thing I can think of being affected.

The stars and points are just for players who want to compete on the leaderboard. Several factors go into the score. It’s not related to your EXP though.
Cheers!
