How hard will it be to explain to you that wehr T4 have much stronger units then soviet or USF T4 and it needs to be more expensive for balance reasons, yet its more accessible with new costs then it was with old ones?
Difference between you and me here is that I have played with the changes for some time(oh look, your first argument goes straight down the shitter!) and you're just talking out of your ass.
Ost T4 is much more accessible then it is with current tech.
Why would you ever want to go T4 other than for a Panther? Especially when for that price you could just get 2 PIV's, or a PIV and a StuG III or just a smattering of StuG III's and Ostwinds.
This patch hasn't solved the issue of Ostheer T4 being aggressively mediocre for what you pay for. It would be a fairly easy fix just to give the Pwerfer it's old rockets back and make the Sturmpanzer move like the crew isn't drunk and lower the cost of the Panther a tiny bit.
T3 has literally everything you need in it, T4 has overpriced mediocrity.
