It's a 230 MP HMG that suppresses nearly as well as a MG42 - it serves it's purpose. I've played the preview patch and it works just as fine as it does now (because literally nothing has changed except for the crew). I seriously doubt the crew shooting at long-max range in the live game adds a significant amount of damage anyway so why is it's DPS suddenly an issue?. It's a 230MP HMG... it shouldn't do a lot of damage regardless because you buy it for the suppression not the damage.
Feel free to post the video of your test (or you know provide details, because firing at Tommies at max range behind green cover doesn't mean a whole lot). Frankly the whole "can't suppress Tommies for 8 minutes" sounds like extreme hyperbole because if the MG34 was that bad now we would know about it. Yes the MG-34 doesn't do a lot of damage, yes it has trouble vetting up as a result, but it doesn't need to do damage or vet up quickly to do it's job. I'm sure they could lower the Vet requirements and that would be fine but that's about it.
Finally someone here understand the reason why build MG-34 !!!
