I think that the French troops numbers could use some looking into.
In my recent game against greenalien I was playing the French and the ammount of forces I had was simply amazing.
By september 1759 I have managed to accumulate 15.000 troupes de la marine, 8.000 regulars and 5.500 militias (and that's without garrisons and artilery/supplies) and that is after the 32.000 combat losses that i have sustained during the 4 years of warfare. With the almost 12,000 indians/couriers I have probably more forces in America than my opponent (and his combat loses are supposed to be 29.000).
I achieved such numbers mainly thanks to capturing Albany very early (indian allies and depot) and Chevalier the Levis who spent the first 3 years in Montreal non-stop training the Militias into TDLM and i was swarming with militia getting bout 6-8 units every year.
I think that either the ammount of militia that the french recieve in this scenario should be reduced or de Levis should lose the training officer skill.
