138Sqn:
Don't know if I'd agree that St Cyr was a "far better" general (although St Cyr himself certainly would have, generally having a high opinion of himself). A better general, I think so. He was not well liked by his fellow officers, while Oudinot generally was. not that that is necessarily a major criterion.
For Field of battle, the rating takes in both the overall quality of staff/comand, and the officer in question. Thus 1812 French have a statndard rating of "Skilled", with some Excellent and some Average. 1812 Russians have a standard rating of "Average", with some poor and some skilled. Even then, the Leadership Die type still undergoes some variation based on a D20 roll fpor each officer (good day, bad day, Chief of staff ill, etc).
So, I could go with Oudinot Average and St Cyr Skilled much more than Oudinot Skilled and St. Cyr Excellent – IMHO he certainly wasn't at the level of Davout, Lannes, Massena, or even Suchet or Eugene, maybe not Ney pre 1813 (and loss of Jomini as Chief of Staff). Overall, for the purposes of the game, I'll probably leave it as is.
