I think i found my problem with this, its not the unit thats the problem. its when combined with troop training, an early vet3 pgrens is extremely powerful. without vet though, they are manageable.
although it means later pz4, but with them being upgradable with schrecks at any time means using armour to counter them may not be the best.
I still think they have too much dps, but at least they are soft.
Elite troops doctrine is OP, not PGrens.
