A digression - for Japan it sounds nice to have more divisions to take more undefended Allied locations on their surprise impulse. But they do have access to a good amount of them in their force pool already - 2 Engineer, Para, Mountain, 2 Marine, 3 Infantry; plus 2 Motorized divisions can invade off a TRS at juicy locations near Japanese bases, like the NEI oilfield hexes. Granted that set of 11 divisions would cost a little bit more than breaking down a few extra INF.
But more divisions for the Allies is hard for Japan in mainland Asia. Instead of 2 Cavalry divisions for the Chinese, they could then deploy up to 8 of them if they forgo using their regular CAV corps, which are pretty weak anyway. I know there aren't "unlimited" divisions - but the USSR could send quite a few of them into Manchuria if they chose. China could also send out more infantry divisions as raiding units as well, and with more Chinese cities on the map...
True these generally 1 factor divisions could be countered, though the Allies might back any one of them with a long-range bomber or ATR or both. But they are dangerous for Japan because what Japan is even more short of than garrison units can frequently be land moves to move those garrisons around as it begins to lose the strategic initiative and is forced to re-act to USN moves in the Pacific. China takes a land action every single impulse.
The USSR also has the nice new fantasy base of Komsomolsk (a city hacked out of the wilderness starting with prison labor in 1939 - not a Red Army recruitment center or depot in any way shape or form) to fight from as well; the Russians should be able to hold onto 1 or 2 of their 5 Siberian cities unless they are totally losing all of European Russia already. It takes Japan a long time to march to and assault all 5 locations.
Should Japan strike first in the Far East they need to basically try to capture all 5 of those cities, or else they will never have a placid Manchuria. Without some economic benefit from a negotiated Peace with Japan, the Russians have zero incentive to ever go to Peace, as Siberia is so much bigger than the Japanese Force Pool.
With the unified map, the war in the Far East has changed from a WWI type of warfare to a tactival theater. There are to few units on both sides to be able to absorb a lot of losses.
This is particularly true for the Japanese! If they go all out for China, they get troubles with Uncle Joe and can't stop him from entering Manchuria. If they go for the USSR, they don't have enough to counter the Chinese oozing through the frontlines...
The USSR and China are somewhat linked to eachother in MWIF. If one supports the other, the Japanese hasn't got a lot of options. That's why the optional rule needs to be coded, because Vladivostok is vulnerable for a Japanese attack.
If the USSR sets up or sends the Siberians towards Persia, the Japanese have the upper hand in the region.
Which then comes back to a German Sitzkrieg. As soon as the USSR see the Germans build naval assets, they know what's going to happen and the Japanese are going to suffer from it. Which means that in MWIF: the Soviets need to set up all Siberian units around Manchuria and use build units out of Europe for the capture of Persia and Iraq.
That's quite a difference if you compare this to the board game...
