Any amount of smoke, or light vehicles, are enough to fight against MG42s early game. Every allied faction has access to one or both of these tools early on.
As are flanks, which can indeed be done against Ostheer MG42s, most 1v1 maps provide plenty of sight blockers and alternate routes to get around strong MG positions.
Following that logic, you can always beat rifles by simply suppressing them or sitting in green cover before they do.
HMG42 doesn't have it bad in ANY way, unless user doesn't know any better.
