btw, TWI named their panzer IV wrong, its not the Panzer IV Ausf G that is in game, butt he Panzer IV Ausf F2 ( the gun tell it all ) and both gun have different penetration value :S
but to come with the thread, i found tho the T-34 very under-powered compared to its real historical fact and ability... for example :
a T-34/76 do yes have 45mm frontal hull plating, but its slopped at a 30 degree, a straight plating will have 45mm, but angle it from 90 degree to 30 degree, what happen to the same point? the true thickness increase, and 45mm angled at 30 degree is now technically thick as 100mm, and if you note on the stats the PzGr. 39 of the PzIV at 1000m only penetrate 81mm + having its speed reduced from the range, a shell hitting the T-34 would not penetrate and bounce instead, doing no real damage, so why a fight with a panzer IV at long range always lead in... panzer IV win
tho even at close range the sloped armor of the T-34 would be still even more efficient, in fallenFighter earlier today, i got killed 6 time in a row, vs a panzer IV, i killed 3 or 5 of his crew, tracked him, engine down, etc, even shooted many shell at him, ( in those 6 lives ) and he was still able to shoot, and kill me until i kill him, as on 6 time, in 1 shot its was either, dead, hull MG and driver dead, turret ring destroyed, gunner killed, why such poor efficient in T-34 armor, when its was superior and able to bounce a panzer IV shell, at medium-long range.
