960hp and 300 armour doesn't warrant a single call in restriction, unless it gets over 1,000 health like the other heavy tanks.
So it can only take one less ATG shot. If it has 50 range, good firepower and better mobility?
It's not meant to be an IS-2 or Tiger clone, but just because it isn't does not mean the restrictions shouldn't apply. Do we want the heavy tank call-in meta to return?
