I roam around in space, killing enemies and completing missions. I just came back from a break, so there is a lot of new stuff including doffs. I thought they were some sort of bridge officers but I was wrong apparently. What I've read so far about them is this: they involve some micro management, there is also some kind of mini-games involved. I assume they generate some kind of rewards, but for me as a pve space roamer, do they give me any kind of buff in combat etc? Why do I need doffs?
