The VK 3601 with the Waffe 0725 gun would be an absolutely useless tank, due to the gun. Why?
Well, it is a squeeze bore gun, there is already one in the game on a german car. The problem is, that the shell is modelled as APCR.
Now since the last APDS nerf, even APCR started to shatter on everything, and deal absolutley no damage, even if it pens.
To top it all up, Gaijin would implement something like a 6 round ready rack for the tank, and with that 6 round, you might destroy a light tank, and after that, your rate of fire will be horrible, with absolutley no damage.
If gaijin models it as a solidshot, then that tank maybe could be good, since the penetration is close to the Panther’s penetration. But even as solidshot, the damage will be bad at best, so the tank should not have a ready rack (so the reload time does not change depending on the ammo rack location), and a faster reload time, maybe 5s aced, but 6s aced maximum.
The armor would be somewhat OK, but since the side armor is 60mm, you can’t really angle it.
The turret is a Panther-like one, so the mantlet in the middle is ~100mm or so, this means at close range potentially even the american 75mm will pen it, not even talking about the cupola.
So it is a Tiger with everything good taken away from it. Armor, that you can’t angle, no magical inpenetratable mantlet, bad damage.
I would say maybe 4.7. At 5.0, you have the Protopanther, and that is just a better at being a “heavy tank” than the VK 3601.
The VK 3001, maybe 3.3. Again, the issue is, that it has the same armor as a Panzer 4 F2 (okay, better side armor, but that does not change anything), same gun, but just slower for no real gain in anything else.
Scorpion 90. Just no. That should be a tech tree one.
The T23? Knowing Gaijin they would put it at 6.3, because why not?!
On a serious note, it could be good at 5.7.
With the T49, i don’t know. The issue is, that it has APHE, that the RU does not have.
So i could see gaijin putting it way higher than it should be.
Other than that, same as the T23, it could be good.
CORRECTION: Forget about the APHE thing, i was mistaken, it is a low pressure gun.
