This worrys me
does it not mean that everyone has exactly the same officers??
also an officer I can't dismiss is probably a spy
It does-at least for the initial arc (levels 1-10). After that, it starts to be more traditional, with both Romulan boffs and your chosen allies' boffs, in that you can modify everything about those. Only your initial set of boffs seem to be locked in their appearances. At least, so I've seen so far.
