Just like the topic says, T-34's are useless for the amount of fuel you spend to get them. They are not good AT until the 85mm gun and by then it's just cost effective to get more infantry AT and SU-76's. Maybe lower the cost of the Heavy Tankovy program to like 90 Fuel and have T-34's at like 60 Fuel. After that give a buff for damage against infantry and turn it into basically an Infantry Support Tank. This would be nice because the only other Anti-Infantry vehicle for Soviets is the T-90.
And don't use title like "(Something) is useless", be specific.
I thought there was like a problem with the armor being bugged where it was super easy to penetrate and damage. I only heard from a guy I was playing with so probably that isn't the case.
You do know that code-wise, the T-34 is pretty much the equivalent of an upgunned Sherman, right? With the 85mm upgrade, it becomes even better.
