Ah, my favorite WWII tank. Nice.
I know it isn't the best, but I like how it looks.
A note on the turret. In the T-34/76 the floor of the turret did not rotate with the turret forcing the crew to shuffle around as the turret rotated. In addition, other than a small number of ready rounds the shells had to be gotten from under the floor grating and the spent shells had to be replaced under the grating. All of this conspired to significantly limit the rate of fire in the T-34/76 after the ready rounds were used.
In contrast, the T-34/85 addressed these issues. The floor of the turret now rotated with the turret, round storage was more convenient and a an additional crewman was added as a loader bring the T-34/85's rate of fire up to contemporary standards.
As to being perked, I don't think it should be. The gun performance is still inferior to the Panzer IV H's. I think the T-34/85 will make a good high end free tank.
T-34/85 = better armor and speed, decent gun, no commander's gun.
Panzer IV H = better gun, commander's gun, poorer armor and speed.
The choice is a trade off.
