Oh please. When you exaggerate you just make yourself look unreliable and biased. And people will ignore you. "less recoil than the mp40"? I don't think so.
This thread is something of a mess. People calling for MG's to be nerfed to oblivion!!!11oneoneone. All because they are moderately good from the hip? And yes, I said moderately. Because as handy as they are in a pinch, they're still not remotely as useful for close range as a PPSh/MP40/MKB.
You have to ask yourself why people are using the MG34 in this fashion. The answer isn't because it's better than the SMG's/assault rifle for clearing rooms. The reason is because using it in its primary manner, deployed, is often less effective in game. The reasons for this have been debated about enough in other threads so I won't repeat it here.
But if you reduced the effectiveness of hip firing for MG's, it wouldn't make the game any more realistic. And it certainly wouldn't make the game more fun. All it would do is make an already underpowered class even more underpowered. And then no-one would use the MG's at all in the small urban maps that dominate in Stalingrad.
The changes the MG's need are to do with deployed usage, not hip firing.
