Man I play Germans as well and I find no problems with utilizing MG42 on the battlefield. This could be to the fact that as a Soviet player I was able to use pre patch Maxim to some degree. Transition from the God like MG to the unit we have today must have been painful for majority of players.
You can even find replay I posted in other topic to support my opinion.
Just so you know, I never used the Ostheer MG previously because I knew it was broken.
Usually, my build tends to be Gren Gren Sniper Gren. If they're massing Conscripts though, you do need the MG.
In that game, there was many times where Scripts were Oorahing through the cone of the MG. With PPSH, they just wiped the MG.
ie, this means the MG has to be notched up in suppression or Oorah has to be nerfed in terms of suppression resistance.
Having a "Fire-up" ability which avoids suppression on a main line infantry unit (not rangers or Airborne) is kinda bullshit to be honest.
