You are acting like this bullshit is unique to 1 faction when it isn't.
As Commash suggested earlier a easy fix for this would be to take squads get pinned way faster, which means they will take less damage BUT they won't be able to just hang out in the LOF of an MG forever.
Not at all. It's just about three times as easy for Ost to do it compared to any other army. Because, as mentioned, the grenade range is enormous. Doubly so at vet 2. Grens don't even need to crawl. They can pop the ability before an MG really has any chance to suppress.
Pinning units faster isn't a requiement, it's a dream for players to have easy, lazy days with never having to actually micro their MG42 and just be able to sit back and watch them single handedly contain entire fronts full of infantry.
Other counters do exist, but they're slow, inaccurate, and generally not so much a counter as a way to force a unit to re-position. Mortars do not counter MG's, they harass them. Snipers do not counter MG's, they harass them (unless they come in bunches of two or three, at which point the game should be a joke.)
We have seen what happens when infantry squads are rendered incapable of forcing MG repositions. We saw what it was like in the beta, when oorah was free. It was god awful. Seriously awful, stagnant, boring play. It was what gave birth to maxim spam, because a 1v1 fight with a maxim vs. MG42 was, at the time, the only reliable way to push the sodding things off.
Underlined and bolded a point in your argument that completely contradicts your disagreement.
The point is that MGs of any kind are pretty incapable to keeping a single unit away from being able to deliver some kind of grenade. No MG can really hold off a frontal assault without a grenade that forces them to move. Most infantry can get into grenade throwing range before even being suppressed, let alone getting pinned.
In many ways this completely undercuts any merit to flanking maneuvers because it's usually more work and risk than reward than simply telling a squad to march forward and decrew an MG for some munitions.
Ugh, no, it doesn't.
MG's render one unit combat ineffective. They will not stop them using abilities. MG's are not meant to one man rambo style hold off frontal assaults at all.
You know who should be doing that? The rest of your infantry. The grenades, if they do get off, should be pretty sodding obvious. I don't get why so many axis players have this crippling obsession with only repositoning their MG once the suppressed squad has started the throw animation. It's probably too late by then. Once they hit the dirt and start crawling, if you can't levy enough firepower to force a retreat on them and they get close to nade range, just sodding pack up, move back a bit and set up again.
Problem solved.
