1. Remove the possibility of having general that costs 0 koku or better; make the general cost same for everyone. (The general upgrades are not in level with the money they cost. The matching system should take care of the difference of general benefits.)
2. Make ashigaru unit upgrades to cost less than samurai upgrades and samurai upgrades less than monk upgrades. (The benefit is bigger; cost should follow. This is balancing part II thing.)
3. Make artillery unavailable for standard games or raise the cost to 4x what it is now. (Not only is fixed artillery vs moving enemy an unrealistic; it is also exploited a lot and shapes the game to really boring one.)
4. The matching system needs fixing. (I'm rank 6... I been autolosing fights against rank 9-10 since I was rank 1. The rank 1 players been autolosing to me since rank 4.... It's not fair; its not fun; its not competitive; it doesnt work.)
5. Make personal banning system that prevents banned player to play with or against you. (I have about 100 russians in my timezone that spend their time figuring how to exploit. I could really live whitout 100 of them.)

Those are the ones I would put up as main issues after two weeks of play. I had some good games but... over 50% is someshort of exploiting. I have lost quite a few games due making tactical error, I have won few when opponent made one... Thats how it should be. Not like 75% of the loses; opponent has better army and steam rolls; unlocked all the units like hero units, camping strategy with arty or smt similar. Game should be won means other than having unfair advantage.
