There is a number of reasons why Pz4 hit the field first
It was because USF and UKF were designed to be oppressive in the early game.. and easily cut off early game Axis fuels. But now they struggle to and the game is even, but nothing else has been patched to change from the old meta.
So now we see earliar T2 from Axis because it's so easy to get map control
5 minute mark
Volks outnumber Allied infantry
10 minute mark
Allies FORCED to go anti tank
15 minute mark
Stug spam comes, lose all your light vehicles or they are zoned off the map
20 minutes
Forced to make more AT guns, die to indirect fire
Forced back to playing soviets
Conscripts are our last good infantry to abuse the early game, and stop fast T2
Even Devm gave up on using USF lol
