The poll favors Prussia but it was Austria who made the main war effort against Napoleon throughout all the conflict, by far, both in resources and manpower / casualties. And thus it would deserve the first introduction as a faction in my opinion, before Prussia or Russia.
I guest Northern German players just don't feel represented by Austria... But as an Alsatian I would rather have the whitecoats in before damn Prussia!
The Prussians should have their early uniforms with the bicorn hats.
I agree with that, so far we have uniforms roughly fitting 1807-1808 I believe, both in French and British faction: French have the long cut uniform, not the Bardin design yet, the british still have the bearskins and the stovepipes. So Prussia should have discarded the kaskett and wear bicorn hats, grenadiers would wear the SYW like mitre caps. And we shouldn't see any of these black brunswicker guys who were created in the late period.
