DPM of T62 is nice in papper. However it is same sindrome like on T54. It does less damage then patton and E50 gun and tends to bounce.
I dont joke even on test server i am bouncing T62 shots from my front.
Turret front armor is nice yes but it is not good hull down sniper for the same reason that T54 is not. It is too small and lacks gun depression. That is job for patton.
Main thing of T62 so far that i have seen is huge improvement in mobility. Secondary is its improvement in firepower. Protection improvement is not so big. Its same philosphy that t54 was.
As i said on paper its gun looks nice but in practice i think both patton and e50m have better guns ( as someone pointed out accuracy and shell speed of apcr shells on e50m is just ridiculously good ).
