Umm, panther is tank destroyer for the last 8 years since coh1.
You can argue against that, but you won't get far that way.
SU-85 costs as much as medium generalist tank and its usefulness is as good as going against medium generalist tanks. Jackson costs exactly as much and while its worse against mediums, its incomparably better against anything over P4.
That's why you see T34/85, IS-2 and ISUs instead of it.
You can again argue against that, but that's another dead end for you.
Panther is a tank destroyer, but I mean it's not a proper tank destroyer with 60 range like SU85, JP4, or Jackson, that's a problem Ost has, which they lack such a unit in their base army.
About Jackson, they improved its penetration because of this faction's design which people complained they have problem dealing with the axis heavies, but do soviets really have such a problem!! lol because Jackson's penetration is improved u reckon SU's should be improved as well!!!
lol I love that you keep saying that "it's dead end for u!" and "u can't argue against that!" it's so cute!
