Yes you're right, that's why I'm asking for delayed promotions.
In RoF Campaign, even in a lower rank, you have the chance to lead a flight consisting of pilots of yours or lower rank, which is good and also historical.
For example I had the chance to lead as a Feldwebel even as Unteroffizier in several occasions, so leading is not at all missed in RoF Campaign, a feature that is great and unique in any sim Campaign I've ever flown!
One more time Cudos to Pat!
BTW I would also like to see more than max 4 planes per flight options...
