Great job with this so far, Bran.
I am currently playing as Prussia and have noticed that French seem to have amazing morale while my guys break easily. I have foot guards in a superior position getting routed by semi-depleted fusiliers fairly quickly, while pretty damn even engagements always seem to result in my guys routing very quickly, while the French always maintain high morale. I don't really have this problem fighting other factions.
Also, my lancers will charge the enemy, but stop and start walking slowly when they get very close to the enemy. Seems to only be happening with lancers for some reason.
