Agreed, Soviets put more heavier armour, because
T-34 have more armor than Pz.IV
T-34-85 > Pz.IV Ausf.J
KV-1 > Panther
SU-85 > JgPz.IV
ISU > Ele
And about 80 HP buff:
SU-76 surely doesn't need that buff, while StuG III definitely need 560 HP
because PTRS are better against StuG than Schreks aganst SU-76.
Thats not what i mean. you see the i2 and isu152 far more then the elephant or kingtiger. and comparing mediums is largely irrelevant anyway.
