That is literally how you use every single MG in the game, the issue is you need to do that with the MG34 far more than any other because you can't suppress on top of being a 4 man squad. It suffers from some of the same issues as the .50 cal, but at least the 50 has a quick set up and tear down time.
The awkward strength of the 34 is you can get a lot of them to cover each other.
It suppresses and its 210 mp... There nothing wrong with this weapon
