I think the inherent problem here is that in most WW2 games, and definitely the MMO games like
World of Tanks and
WarThunder, the German equipment is consistently (with exceptions, of course!) matched against that of the opposing nations that was designed to take them out. You rarely see Tigers and Panthers fighting swathes of the early- to mid-war models of T-34 and KV-1 - those they easily trashed in large numbers and earned their fame with - but T-34-85s and IS-2s, instead, maybe even more modern ones. While that's totally fine and
fair from a gameplay point of view, it's not surprising that the fanboys feel
over, because they can hardly ever play their beloved vehicles in the context they actually fought in.
But here's the problem: Giving the German fanboys what they want will just turn the situation around, and cause
everyone else's fanboys to whine. Yes, they do exist. And yes, I do believe they'd be just as whiny, or even more so, even, if they'd just be given sufficient reason to do so. I'd expect a lot of "nazi cards" being drawn against any developer going down this road...
So, either you put up with the whiny German fanboys, or you get the fanboys of everyone else to whine. Your choice. The way I see it, everyone probably puts up with the German fanboy whiners, because they're still in fewer numbers than those of every other nation combined.
