They are still a powerful unit, but now they will lose the fight at long range vs rifles and less often vs conscripts. That's normal since they are armed with smg.
They are not armed with smg they are armed with assault rifles. SMGs are only good no close assault rifles close-mid range. It's a joke that sturmpioneers were nerfed, this will lead to more abusing and cheese and lesser possibilities for okw to defend against it. And nearly every allied core infantry was buffed, and the sturmpioneers were nerfed which is definietly a great idea.... And guys numbers are a fine thing, but thanks to rng they really don't do that much and the term "Midrange" is not really defined.
