The T34/85 does not impress me in my initial runs. I hit a panzer 6 times, 4 hull and 2 turret, at 1700 from the front and it lived. Took 8 hits on the sorties. 2 turreted me, 4 killed me, 2 did not damage me. The closest was ~1400, most were over 2k. The hits that ricocheted were all over 3k.
HVAP was useless over 1600 as I made 10 hits on different panzers without causing damage.
In short the gun seems appropriately modeled.
Its ability to climb hills either directly or across the slope seems poor, but its cross country level speed is 35. Reverse is also quick.
Views are pretty good when set correctly.
It should not be the all conquering GV that some thought it would be when it was announced.
