Not bad but removing PS from B4 should go along with reduce scatter with vets.
I belive KT should have 400 instead of 375.
Ahh... No love for SU76 and Stuart
And did you see all this new stuff??!! Me neither
40+80+260 = 380. That's the cost of 1.6 IS2's.
Increase IS cost to 380 and give soviets ability to deploy self defensive structure and forward med point and I'm good.
Point is, your assumption is stupid cause you don't tech to get KT. You tech through the game because you need it like all faction but in the end you are rewared with best tank in game which is non-doc so stop adding tech costs like it was OST where you don't receive anything.
And let's not forget about cost of T3 or T4 once you decided to go for it because suddenly IS2 costs 350 fuel
Adding tech cost is just pointless.
