I really would love to see cooperative space missions. I LOVED the space missions at first, even though there are many complaints about the on-rails approach. However, I quickly got bored with the lack of variety for the actual missions. One of my first thoughts was "this would be great with at least one other party member" and now the thought of having an operation-sized space combat mission is just getting my hopes up that much more for any kind of cooperative addition to the space combat missions. Maybe even PVP space missions? Though I don't have any creative input on how to support that using the current system.
