Skill difference between nations

Lately i started to play more and more on teams other then Soviets & Germany and the skill difference feels insane between the nations.

The Soviets which are my main army are pretty well matched against the Germans on the BR II and III where i play and grind now with the Soviets having a bit of an advantage on BR III due to the Spray & Pray PPSh-41box needing very little skill to do well. But my teams seem to do about the same regardless which i play.

But once it isnt Soviets vs Germans it gets wild the Western Allies seem to be doing much worse then the Germans & if they cant spam M4 Shermans the game isnt even close. The teams just feel extremly useless, rallies almost never happen, half the players are cowards not even trying to play for the objective or spamming the M13 GMC vs Panzer IVs.

But the real brutal difference when its Japan vs Allies those games are allmost always a one sided stomp for Japan, while around BR II-III where i am now Japan has clearly inferior gear… BAR is a bit better then the KE7, Allied tanks are way better then the Japanese ones, their AT guns are better too. Still except for a few miracle here and there Japan seem to be winning by a landslide & if the allies manage to win a game that is usually a very long and close one.
