At the nubbins level it seems to make a huge difference. They still miss a lot and still die easily but Pioneers can't just ignore them and cap a point anyway, even shreck blobs have something to fear as long as you see them coming ( hint: if the coaxial is firing you are too close).
You can even use em against garrisoned MGs without wasting both time and ammo on both sides.
I love it... Seeing an OKW player reaching for a Pak rather than just expecting to stomp me was, shall we say, a refreshing change.
