Welcome to the boards, and thanks for the feedback.
I think you're right about China's UP, it's quite easy to abuse it and they are too clearly a tech leader in the early eras. Korea's defense deserves some buffs, at least for the AI (which could also benefit from some axemen to counter swordsmen).
The unwillingness to attack / suicide DoWs are likely caused by the AIWars module, which basically declares war based on occupied territory without completely notifying or asking the AI about it. I'll see if I'm capable of making it a bit more intelligent with what I know about AIWars.py and the actual player AI.
