Okay, so something that's been bugging me since I started looking at Only War is that it seems really hard for Commissars to get fellowship advances. They don't get either the Social or Fellowship aptitude from their career, so unless they get it as part of their regiment, Fellowship ends up being one of there most expensive advances.
Considering that they get +5 Fellowship as part of their career, and they're meant to be charismatic individuals (not necessarily likeable, but certainly good leaders), lacking these aptitudes makes it really hard to be good at commanding…
Anything I'm missing here? Is there some other source of aptitudes? Or do FF just think Commissars should be grumpy unlikeable gits?
