Japan-USSR border requirements, thoughts on balance

[MoongazerSlitherineSSL]

I don't understand why it is a requirement of any unit, not corps or army, like in the case with the Chinese warlords in Xinjiang and Xikang. Right now Japan player can just stuff Manchuria with cheap garrisons and bring the Kwantung Army against China, pushing it into the mountains in a matter of several turns. Capturing Changsha and Luizhou connects the entire Japanese territory from Seoul to Rangoon and Singapore, greatly boosting both Japan's reaction time to any threats, income and defensive naval capabilities due to high supply ports. There is absolutely no reason not to do it from day one and I think it kind of limits opening plays. Historically this also makes little sense, Soviet-Japanese relations were quite sour all way through and such weakness in Manchuria would not have gone unnoticed by Uncle Joe.

I think it would make more sense too if those hexes had the same requirement as those two hexes in west China that require a corp/army/tank.

At least they made the Manchukuo, Nanjing and other Japanese minion units ineligible for fulfilling such garrison requirements.
