I don't think comparing two different political, economic and philosophical systems is an appropriate analogy to video game balance. Besides nobody (at least, nobody sensible) is arguing for across the board nerfs to WFA & brits, or removal of their interesting mechanics. What we are trying to say is that if there are a few units or features that are overpowered it makes more sense to bring them back to a more reasonable level.
More on topic: I don't think the powercreep has been contained to just WFA. The recent patch contained primarily buffs for Ostheer and Soviets, mostly buffs with some nerfs (net buff overall) to USF, no real change/slight nerf to Brits, and a nerf to OKW.
Believe me when I say it that I've seen forward retreat and automatic repairs (from OKW for example) or at least the high repair rate of the WFA being superior to that of the EFA being nerfed being suggested.
And the political comparison is the closest thing I could thing of at that moment but yeah considering it was very late night you're kinda right about it now that I think about it.
Still, why not bring up a few EFA units up to WFA levels again, instead of nerfing them. What comes to my mind first is the EFA main line infantry units, those being the Grenadiers and Cons.
I mean, how are you exactly going to nerf the KT down to Tiger levels without losing any credibility for the game being "realistic" (what little realism there is left) and without an uproar from the Axis player base? Of course this just an example but I think you understand what I'm talking about and I agree that there is a gap that needs to be bridged between the WFA and EFA before the support for the game ends.
