Volks will not really die any faster to traditional squad wiping mechanisms, they will merely not be immune to small arms fire (artillery and tanks don't "hit" a target, they just miss close by). The fact that OKW is muni starved is GOOD. OKW was designed as a faction that was meant to have to make tough decisions. Now they finally have one, do I want better AI or better AT?
I agree, raketenwerfer was considerable buffed so you might not need any pzschrecks at all as okw. 60 munis are two nades, it's not much. Especially since a wall of raketenwerfers becomes now suitable. It's only a lot for people that go 4-5 Schrecks and throw nades at every engangment.
Just adapt to what the patch offers you...
