The T34/76 definitely under performs. Compared to the P4 and Sherman it has worse AI (even before the pintle gunner upgrade is taken into account) and worse AT with none of the survival abilities both those tanks have. Sure it is 10 fuel less than a Sherman and 25 less than a P4 but it ends being too expensive to spam and too cheap to be useful as a generalist.
A few ideas to fix the problem:
1.) Replace it with the T34/85. The T34/85 would have to be reduced to the standard 640 health instead of it's currently ridiculous 800 health for this to work and even then the tank would have to cost between 120-140 fuel but the improved gun would make all the difference when fighting heavier armor.
2.) Give the T34/76 HE rounds. It works for the Sherman. If the 76 could switch between HE and AT rounds it would be a much larger threat to infantry and have a better defined role as an AI tank that can do a bit of AT work if need be.
3.) Make the T34/76 cheaper and reduce the pop cap. If the cost of the T34/76 was reduced to around 80-85 fuel it would be a much easier tank to spam in large numbers. In this instance the advantage of the 76 would be that while an inferior tank in all regards you can have two 76s for every panther and three 76s for every two P4s. Thus some degree of parity could be maintained by numbers alone.
