Dont ever use full auto with MG34 and you'll be fineDP-28? Worse than the MG-34? Surely you jest, good sir.
I'd take the DP over the MG any day. I can fire the DP without my 5th shot flying into the next county thanks to the recoil bouncing my barrel into the sky.
Please, don't "fix" the DP or nerf the MG. It's so easy to get my favorite class as it stands...
