I was hoping for such a mission--where you might be faced with yourself. It would be a hilarious situation, and a tough one (as the AI has access to everything you have on your ship; you have no upper edge on a ship of your own strength except your wits--and hopefully, your Federation convictions).
I don't see a strength in those Fed/SF convictions, more an... annoying hindrance. ^^
Apparently, a Terran Empire Faction appears really attractive to many players, including myself. And it should be relatively easy to implement, compared to a completely new one. All the same ships, stations, races, no additional balance issues... hey Cryptic, hope that wasn't too subtle?
