Seems to be you. Note how in that equation there´s no Ostheer unit but the Tiger ace (which again not everybody has). The King Tiger and TA don´t have 70 range like it´s demanded on the SU-100. Neither do they oneshot squads to the extend of an ISU. Just imagine Germans got an ISU added to their JT... it would be shit in multiplayer. The same thing as Allies shouldn´t get a super range AT tank. Super range AT + Super range AI in one team = gg.
Yes but the Jgdtiger + Axis heavy have other forms of synergy and not just range. They have ridiculous armor and firepower. You seem fixated on the range aspect of the tnaks and not how they function in their respective armies/ opponents armies.
SU100 still would have the weaknesses of a nonturreted tank.
Please think about how it would fit into the current Soviet lineup. Soviets have to rely on call-ins just to deal respectable damage to Germany heavies. ZiS, T34s and SU85s don't do squat versus armored beasts like the Panther and KT.
