Apparently people are not yet sick about getting new desapointment because of bugs, performance and balance problems. All they need are 6 - 8 - God knows how many factions. It's already ridiculous that USF can play together with Soviets in team games - that actually never happened. Now we will have brits aside Soviets? Oh Lordy.
Why do you care about this bit of realism so much in a game that cannot and does not claim at all to be historically accurate?
I understand the bugs and balance arguments, but realism and CoH? Look at the Total War series, in Medieval II you could conquer English soil with Italian troops?! Heresy! Historically impossible!!
I think it's quite cool to be able to combine US and Sovs, even if they didn't directly fight together. If I wanna have realism, I watch documentaries or movies that have a claim to be historically accurate and authentic.
