I'd like them to work on the nations they have.
I think all current nations need some more fleshing out of the regiments. The musicians from the UK have no fighting counterpart. There is only 1 officer class when at least
a rifle officer needs to be added. Officers for other regiments/companies would also be good, namely prussian line (not only Freikorps), Voltigeurs, Vistula, Highlanders (no Highland drummer?
), French and Prussian guards etc. It seems a bit too streamlined and just purely focused on the class system they have.
This of course only if it in now way at all impacts the other updates.
(I guess I will have to clarify that the above is my opinion etc.)
