Never understood the whole "immersive" side of Coh2 multiplayer. For me, as long as the units and combat move fluidly and plays out in a semi-realistic manner, I could care less about the historical side of it.
Well, CoH2 selling point is rough battles with germans against soviets on eastern front.
New armies will add to the game, but will kill immersion, because they do not fit these battlefields, not to mention scenarios like Americans and Soviets in one team.
Well, this speaks for itself when it comes to immersion.
