I have read through most of the other post and concure on most issues. Battles are far too short, with unit sizes of only 200 men at maximum and even the baseline levy infantry's rifles being very accurate and deadly, units are destroyed very quickly. Same with naval battles. Ships burst into flames at the drop of a hat and exploded far too often. I had ships blow up in every naval battle Ive fought. Ships are too fast in my opinion as well. So to reiterate...
-increased unit sizes
-range tweeks (more for arty, less for early game rifles maybe seeing as they were obsolete)
-slower ship movement
-SMOKE! I miss N:TW smoke. (although i do realize that less guns and better powder means less smoke)
And finally i feel like theres barley any reason on either side to use the old style units. I have played as both the Imperial and Shogunate forces, and on both sides basically just found myself making a mad dash for the best rifle units. My current game i made a concious effort not to moderize, but still hit level 4 pretty fast and havent used my kachi units much. I dont know if its feesable, but I'd like to see either better bonus's for staying traditional, or bigger penalties for modernizing.
Does anyone else feel like siege battles are a joke now?
