You seem to not know much about anything in regards to how these vehicles actually performed. Let me be a little clearer. The is2 could not penetrate the king tiger frontally, in a few situations where king tigers with poor quality alloys were used the frontal plate of a king tiger would eventually crack after a few hits. This has nothing to do with actual intended performance or faulty design. Its more to do with indirect means such as low resources for the german war effort. Do you also blame tanks for the countries inability to provide fuel for it as well?
Is2s did not penetrate king tiger tanks under normal circumstances. For gods sake learn a little something about ww2 before you try to argue balance in terms of historical nature.
No no i know of the perform of these tank. And you pointed out that the IS2 on paper can pen the tiger 2 from the front on paper. But, in practice it did because of poor steel used to make the tank. This is what get under my skin about german WW2 fans (note i dont hate them
). It is just that people in general put too much stock into paper stats of WW2 german weaponry especially their tanks, which were in real like nothing more then a stupid and impractical dream of a made man, with zero thought into functionality, or strategic use of limited resources. Germans during world war really didn't need anything bigger then maybe a panther thought out the whole war. Which which other then the upgunned panzer 4 in my a opinion were far better tanks then the tiger 2. Granted the panther also broke down a lot. There were much better then tigers, ele, the Mous and other large waste of resources tank, arty like rail way arty, or super weapons that hitler thought would win him the war. But in the end these things just wasted already low resource that could of been used better.
This is one of the man reason that i have never and will never like any german faction in any WW2 game I play. This is not because they are german it is because any video game german faction celebrates these dream toys, which in my eyes are the main reason for the germany lose. While faction like the soviets and usf get punished for winning the war though better use of their resource making tanks that may not of been the best on paper, but were better tanks were it counted (Mobility, reliability, ease of production, and numbers to make a difference in the long run). I am not saying that these faction didn't make faulty weapon systems (soviet land ship anyone, or the Super USF tank), but they were smart enough to go back to weapons that worked.
I would also be careful about this statement "For gods sake learn a little something about ww2 before you try to argue balance in terms of historical nature", because your not that much better. 75% chance for a IS2 to penetrate a tiger 2 with shitty steel armor, and weld job is a easy way to bring some Historical facts into the game.
