I think there are some “new” asteroids in a few missions like in pocket 1 of Downing The Slavers and Rogue Drone Harassment. But they all look and are oriented the same. I guess they exist to be an obstacle of some kind. They don’t look good.
I would like a public and competitive bulletin board for missions instead of getting just one mission offer at a time.
In addition, I would like if you could accept more than one mission per account and agent if you have the right reputation (or skill).
