Would it be possible to modify the game so that every crew member would have Qualification ? Like Officers have now 3 slots and NCOs have 1.
I'm thinking about Seamen having 1 qualification (since everyone is trained for their speciality, especially in sub), NCO having 2, and Officers 3.
I know I could make all crew NCOs and Officers...but...

It'd make crew management bit more interesting too, IMHO. Now there is no difference using machinist on bridge or helm and vise versa.
