Appreciate this detailed response. But it begs the question. If you know this, and most know this, how do the devs not know? Are they aware that the UK never defends it home isles, or that Germany makes stupid builds as you pointed out? It seems like they expect we the customers to fix their poorly designed games.
Not sure what definition of "broken" you're using, but Germany's invasion of the USSR did fail, and it's entirely intended that it's difficult for Germany to win. Is France also broken? They hardly every hold off the German invasion...As for "stupid" builds, Germany did have an overwhelmingly infantry based army, ran out of Manpower in Russia, and did not build any strategic bombers. Now perhaps ingame it's more optimal to build only CVs, strat bombers and Paratrooper/TD divisions but if we do that people then would say how stupid their ahistoric building was instead.
