Hmm, this is a good point, but then, ranks vary amongst the races as well. While rank 4 is usually security personnel, rank 5 can either be a totally expected pest controller, or unarmored academician. Rank 3 is either medic, or Bodyguard... Even more importantly, hostess is rank 7 which is usually a terror unit. There is simply not enough ranks to cover the entirety of functions you find in Piratez (I think some sort of unification would be possible, but at the price of variation... you can have > 8 ranks now, after all). Although I think I can adjust this at least a bit (a slight problem being that hideout attack crew has to be the same as Cruiser crew, for continuity reasons...).
In short this is major work and I have a lot of things that have a higher priority now...
