JT can hurt infantry, therefore we should remove stock PaKs.
That's the level of stupid idea you've climbed on.
That is the path you choose. I say since years Jagdtigers rotation is way too fast for what it is. It should be an unit that shouldn't be build in 1vs1 and 2vs2.
Zis3 is weaker than PaK40 because they have non-doc long-range tankhunters. If Panther gets 60 range also PaK40 would overperform.
It is a play of needed micro. And if both line-units have a snare it is more difficult than if only one has it. Zis3 is more resistant than PaK40 and Ostheers tanks doesn't have an real AI advantage to deal with that like e.g. soviets can.
It isn't much, but the fraction's design benefit is clear.
Edit: ISU overperforms, because it can count on the rest. Elefant it good, but it is fighing with an line-up doesn't able to perform as evective or pop-cap doesn't allow any real use.
