My understanding of why the single pschreck is bad is because it deals 120 damage on penetration, which means in order for it to be worthwhile over the raketen which deals 160 damage, you need some kind of follow up to the schreck, be it another schreck shot, which requires a reload, or a snare. Without any follow up, it will still take 4 rak shots to kill a medium tank, and 3 rak shots for a light. It simply doesn't do enough on its own fast enough. Also being on the sturm sqaud which is expensive, is a semi combat unit, your sweeper, your mine layer and your repairs make it just another burden on that unit.
It was, but it was compounded by several other factors.
The five levels of vet used to have a more impressive combat bonus.
Hitting a vehicle with a shreck used to be enough vet to jump a whole level for volksgrens.
There was no Mg34 for OKW to invest in
It was a combination of dumb. But I still think that handing shrecks out to the freely available mainlines with snares is a bad call unless its doctrinal. Too easy to focus into early AI vehicles and let the infantry pick up the slack.
Just saying, volks didn't have snares back then. They only got them when screcks were removed. And pfusi isn't supposed to have snares with double schrecks. So there isn't a squad in the game that is supposed to have schrecks and snares. But yes, schrecks + snare is dumb.
