And PF have seen their price reduced because they were too expensive. Obers have finally seen OKW T3 more affordable for their deployment.
And both unit are good at vet0, PFs have utility volks are lacking when hitting the field and this solely make for their initial price. In definitive every unit is designed to be better with vet, nothing new here.
...
You might want to debate PF with the MOD team that clearly explained their design in the patch notes:
Panzerfusilliers
The way Panzerfusiliers are deployed has been changed to better match their role as an alternative mainline infantry to Volksgrenadiers. They will be slightly weaker than Volksgrenadiers at the start but have access to the Anti-Tank Rifle Grenades,
slightly better combat veterancy, and more powerful upgrades, giving them increased power in the late game. This should make for interesting choices and compositions.
And my point is quite clear if this design has made it the game it can be applied to other units also.
