Volks has nothing wrong in 1v1, instead, the screcks are essential for survival.
They are, but giving them to sturmpios would be better for over all balance.
After all, ostheer can only get schrecks for the PGs, which btw is a pretty expensive unit. It doesn't make any sense to get schrecks for your cheapest infantry unit. With a small raketen buff it would be just fine.
