Yeah I think a heavy tank should reliably kill a medium...
And that's a medium tank counter, AKA tank destroyer! Whether you like it or not.
You can call it otherwise mr semantics, I proved my point and I'm done here.
Now what you just said is even worse, because not all heavies reliably kill mediums, for example sturmtiger. Or are you saying we should buff it too?
Even Jagtiger can be unreliable because it gets flanked easily, did you mean to buff it too?
