They should probably scrap the t34/76 all together and just replace it with the 85, priced accordingly to its power. Replace the t34/85 in commanders with an ability for the tank that makes sense. There is never a situation where any decent player thinks to himself "Hey, I could really use a t34/76 right about now".
There is if t-34/76 is and early callin that you can get to counter stug e, command panzer, pumas, flak ht, or luchs rush. Its not a bad tank. Its only looks bad when it is placed as the end tank in tech tree as if it was a panther.
