Not much time have gone afterpatch, people adopt slooooowly.
There is no problem in pgrens with pshreks, problem is that people want a T70.
Before patch T70 was a great choice against ostheer, because ostheer needed to bring in field more manpower and munitions just to counter it, or suffer from bad map control while T70 is uncountered.
Things havent changed, there still be another option for soviets in case of pshreks on field: the quad.
It is cheap and you pay exactly the same price for quad upgrade than ostheer for pshreks. Quad definitely will stand against pshreks because of suppression, and force ostheer to get a pak for countering. T2 is not skipped, voila.
(btw quad and T70 is deadly combo)
People just are accustumed to build orders, and they need to change them after this patch.
+1 good post!
