Now there is no incentive for the construction of T-34-76. He comes at the same time as the Pz4 which beats him as an anti-infantry and anti tank. Or a little earlier than the Panther if the German does not go to T3. Maybe in 1 vs 1 this has a meaning, but in 2 vs 2 and above in T-34 there is no sense.
Medium tanks getting obliterated by the saturation of team weapons and tank destroyers is a problem with teamgames, not a problem with the T-34/76.
As I said, I think it could do with a +20 penetration buff, but putting it in T3 is insane.
