Well, I learned a lot since I posted this question. At that time I did not know much about the different unit types. You have to play a few battles to get "to know" the units really and what they are capable of. Also it helps if you have good generals - and I did not really have them because I did not develop them. Also, I did not trade enough and did not concentrate on a few provinces to develop arms production, instead I had a lot of low quality units and a few similarly developed provinces. So I did almost everything wrong but hopefully I am getting better... ;)
