I really like the idea of STFs, and I can't wait to actually get to one, when I've leveled that far. But I'd like to suggest that these missions be converted to the normal single-player missions, later on.
I've seen the trailers announcing these missions, and it seems like the stories are fairly important to the overall story that's happening in STO as a whole.
I may never get to experience the STF's without getting together a good crew, and as I prefer to do the missions by myself most of the time, it just might not happen.
I realize the missions are designed such that they are extremely difficult, and require a team of people to do, but I also realize I want to go through them, at least so I can see the whole story of STO.
