Hello!
Small thing that "irritated" me slightly is that when you get FF that gives you free promotion, that you could and might have aquired through experience it is wasted on old veteran units.
So solution would be either:
a: When FF gives you free promotion existing free up, and players could choose another promotions instead
b: FF gives promotions / bonuses that are unique. For example the FF that gives hills combat fighting all units receive the bonus and they can still have the regular hill fighting promotion.
