So OP wants to remove suppression from MGs? Nice way to stop blobs, lol.
MGs at the moment must not be played as agressive as they used to be. They neither are first line units nor Maxims that can a move their way through the map. An MG needs baits. If the enemy comes with the blob of hell and sees your lonely gren squad in green cover he will try to overrun them. But 1 or 2 MGs behind the enemy's sight will push them all down to the ground. Remember to defend your flanks with troops or mines.
Complaining about MGs is most of the time simply a l2p issue and I say that as a 90% German player. You can't just rely on one MG against a horde of US rifles. Imagine how D-Day would have been with one lonely MG behind a sandbag: "It was nice to serve with you, Fritz."
Too many players think "Okay I built my MG. I don't need to get a second one."
Sure the US player can push through them with smoke nades but that's what smoke is for. Germans have smoke too, you know, and it's even free and comes with every mortar.
