You're comparing one tank to one tank, and only in one aspect: armor.
What about how the T-34 compares to the Tiger? What about how the penetration power of the guns compare? What about how the T-34 compares to the later model Pz IVs? What about issues like reload speed, commander cupolas, sight differences, and the like?
You can't get a complete picture of balance unless you take the entire force into account, AND you look at other advantages and disadvantages that the tanks have.
Yes, the Pz III has weak armor, but it's also got a wickedly fast reload speed, and it's got a low profile which means it's great for ambushing. It's also got better optics than the T-34. So, yeah, if you try to drive it like you would a Tiger or a Pz IV H or F2, you're gonna have some trouble. If you drive it using, say, shoot-n-scoot tactics, or as if you were in a T-34 going up against a Tiger, you may have a better go of things.
Regardless, none of the issues you've raised have anything to do with what I was talking about originally. Someone raised an issue challenging how someone else used "gameplay", to which I responded that it was being used to denote the balance BETWEEN FUN AND REALISM, not between the Pz III and the T-34.
I get the sense you've got an axe to grind over this issue, which is why you brought it up. And yeah, IF the armor code is screwed up, then I'm all for fixing it. But comparing the T-34 to the Pz III isn't that different from comparing the Pz III to the T-60. They're not supposed to be "balanced" in the sense of "equal." The map in general is supposed to be balanced, but the tanks themselves should generally have realistic values as far as what RO tracks. If the T-34's armor values aren't realistic (and you haven't shown anything yet to back that up), then hey, let's fix 'em.
But if the issue's simply "It stinks that I can get killed by a T-34 when I'm in a Pz III", well.....you won't get much sympathy from me. It stinks to be killed in a T-34 by a Tiger, but I'm not complaining about how the Tiger's overpowered and the T-34's gimped.
I do agree that there's some issues in how the armor numbers are run, but I have a hunch that's more an issue of algorithms than the armor values of the tanks themselves.
