Compare to other faction’s MG nest, Germany MG 34 has the fastest rate of fire(800-900 RPM), and other country’s machine guns are only about 450-600 rounds per minute, which are difficult to use in high Br.
I think the original MG nest could be remained for low BR, but need to replace the MG34 with the MG08, because its rate of fire is about 600 RPM and was also used during the war.
To make the MG nest more suitable for high Br, using machine guns that have higher rate of fire(over 900 RPM)is necessary.
I also wrote a topic about the scoped MG nest for sniper squad, I think MG 08 with scope would be more useful than MG34. Especially from long range, slower rate of fire is better for accuracy.
