the chinese DAIM seems to be way to pafic to me. However it is also like this before the mod too. So I have come to the conclusion, after some tech tree twiking that techs for Nat. China that need to be required.
First Mobility focus and human wave need to be enabled in land doctrine.
Making all troops for Nat. China '36 style (reason, Japan will get 39 early and the stats for 36 aren't that much better than '18 ones; considering 18 years difference has pasted. this helps with a level playing of '36 vs '36, but as soon as jap get more adv in artillary and infantry, China is easily taken out by the AI)
enable all great war artillary, this is more for game play rather than for historicial accounts.
the first three air doctrines enabled at the top e.g. fly circus
