I'm not sure if the issue I'll write here has been discussed before. But I'll have to try.
I don't know if it's gamey WAD modification or not, but I found some mistakes/underrated value around Manchurian provinces.
1. Railway
Reference:

A) Wrong Route:Siberian Railway
Siberia Railway doesn't run through Borzja and Tahe, but Tjita.
Suggestion:
1)Upgrade infra of Tjita to 50
2)Downgrade infra of Tahe to 34
B) Not considered ?: Chinese Eastern Railway
Russia constructed Chinese Eastern Railway in Manchuria. It connected Tjita and Vladivostok via Harbin. It was finished earlier than northern route(current SR in game). In 1935, Russia ceded all CER to Japan.
Suggestion:
Upgrade infra of Hailar, Oroqen Zizhiqi, Qiqihar, and Jixi to 50
C) Not considered ?: South Manchurian Railway
Chinese Eastern Railway's sub route ran from Harbin to Dalian, though it was taken by/sold to Japan later after Russo-Japanese War. Japan poured large sum to enhance South Manchurian Railway. In 1934, Asia Express Train began to run from Dalian to Changchun(it was extended to Harbin next year). It could run 130 kph in operative speed, and regarded the fastest train in the world.
Suggestion: Upgrade infra of Harbin, Changchun, Mukden, and Dalian to 60 or greater
2. Territory

A) Should we treat Manchukuo as a nation?
Manchukuo put her defence in Japanese charge. Japanese army garrisoned all along Manchuria-Soviet Union border. Considering Japanese-Manchukuon relation/interaction, it may be better for us to give Japan all Manchuria as annexed province(like British domination over India Empire). If human Japanese player wants to found independent Manchukuo, he can liberate puppet her now(thanks to 1.05c feature!).
If not, it may be better to make Manchukuon Manchukuon-Russian border provinces under Japanese occupation(like Manchukuon-Chinese border). It'll work better for AI, as AI NEVER garrison inside other nations' territory.
