The PzIII B is so unbelievably bad and unbalance compared to even the t60. I’ve played many matches with it and its very easily knocked out with out much trouble at all destroyed by the 20 mm of the t60, where one from the shot is never enough to knock out the t60 or even pen the front of it. Even if you manage to pen the turret of the t-60 it just magically disappears with no damage to either components or tankers. the pzIII cannon is made pointless as it is slower and less effective than the pzII . the pzII is better for some reason even though its the first unlock. Its a slow grind to the pzIII for it to mean nothing 
The PZ3 B didn’t even see service in Moscow. If the BA-11 got removed do to it never seeing combat in Moscow then the PZ3 B should replaced by a PZ38 T to fight against the T60
The Pz35t or Pz38t would actually be the T-26 counterpart.
mistyped, I meant to say the BT-7
The Panzer 3B really needs to be replaced with a different tank
it only has 15mm of frontal armor, making it the least armored vehicle in game right now, it has half the armor of the other 2 German tanks and its armor is so weak that it can be penetrated by a T-60 at basically any range from the front, while the other 2 tanks can block T-60 rounds if they are 100 meters away. The 37mm isn’t good enough to justify the bad armor and average mobility.
The Panzer IIIB definitely HAS to go. Why put a tank that only saw 10 units produced in as the first “Upgrade” Wehrmacht tankers get? If anything the progression should be Panzer II, Panzer IIIE and then Panzer IIIJ with the short 50mm. All can be penned by the T-26 and BT-7 Frontally and from the rear by the quick and zippy T-60.
I personally think there should be 3 tank squads to progress in:
Light tanks
Medium tanks
Tank destroyers
This would make tankplay much more dynamic, as there would be 6-12 diffrent possible tanks on the field with their own benefits etc. I’ll make a seperate thread for this.
