I don't have enough fingers and toes to count the Axis nerfing threads on this forum, especially those related to OKW. It's amazing what bias can do.
Unfortunately you are so right man! It is getting boring..
Back to topic:
I think Grens with LMGs are fine. You can easily deal with them playing as US. Playing as Soviets it is a little pain in the ass in the early game if you counter them with conscripts without molotovs. But in mid and late game there are so many Soviet counters that Grens will drop like flies. So nerfing LMG? I don´t see any reasons for this intention.
Edit:
I forgot to mention the high costs of
90 60 Mun if Ostheer player wants to equip a single Grensquad with LMGs.
