Each tank had good and bad sides. P4 was more comfortable, with better optics radio and MG on top of it. T34-76 1941 mod. (t34-76 mod.1943 it's almost new tank, so many and huge were improvements) has more armor, better manuerable, but lack of comfort (hell heat in summer, troubles with start in winter), bad optics, unreliable radio. As one soviet tankman said "T34 is the best tank for serving in peaceful time".
A russian tank with problem to start in winter ???? I know Germans had such problems. I know for sure they could not stop the engines during the coldest winter or had to make fire under the tank to start them back the following day... I did not know T 34 had problems...
Still It does not answer the question: Why the Zis 3 76mm canon of the T 34 is so shitty in the game... It was a balance question aiming to stick the reality of the machine, not an historical question....
I just wanted to point 2 things : Russian have no Mobile turret tanks able to down a large tank. and the SU 85 or ISU 152 are very low compared to Jag and Elephant... This is where the trouble stand for me... The fact that russian have no mobile anti tank option in the game while they had amazing sturdy tanks... ok no Radio, bad optic. Give it a low accuracy (it has it already) a poor fiel of view (it has it already).
But it has a wonderfull canon. give it the punch it deserve especially because russian have no such thing in their arsenal.....
Be honest when was the last time you made or saw a T34 helping to win a game....
The T 70 is much more usefull than it... the P4 is outclassing it...
I honestly think this tank is made unjustifiably useless in the game...
