Theoretically a Fleet Admiral should be a 5 star admiral right? Or are they a fleet adm in name only and as such head up a whole fleet worth of ships, maybe even multiple sectors worth.
For the sake of nothing else I'd make a Fleet Captain a 5 pip rank. And a Commordore a 1 star Admiral.
But thats just me
