I agree 100%. I was just replying to why I think OKW Tiger was not the only solution to enemy IS2. Tiger is ten times better than Panther when it comes to AI so it is a better investment overall, however when we're speaking about countering IS2, Tiger is not much better of AT tool than Panther. Tiger has a bit of ROF advantage and is just more universal with Panther being more mobile, having vet0 range advantage and marginally higher pen.
I'm not sure the Panther
does counter the IS-2.
If you build a Puma to counter a T-70, the Puma's probably going to kill the T-70. It doesn't matter that the Puma's got barely any anti-infantry power because the smoking husk that used to be a T-70 has
none.
A Panther can stand up to an IS-2 but it doesn't reliably
kill it. You get the same standoff as you get with IS-2 and Tiger, except the Panther isn't obliterating models at the same time.
By contrast, the Tiger can hold off the IS-2
and keep pace with it in manpower bleed.
