Through out this past year that I have been on this forum, I have seen MANY Players post requests for Things to do While Flying Around the Sector Space.
My Short Time Playing around with the DOFF System so far shows me that this request has, for the most part, been answered. As you fly along now, you can work on all of those assignments for your New Crew Segment. Then, you add in the Popping Here and There to pick up Commodities you are sort on for some missions, and your Travel time is now full.:p
