OP, what is an MMG? Mega Machine Gun? I’ve heard of LMG, but please excuse my ignorance.
Also, you don’t mention on what platform you play.
Lastly, why do you say no zoom optics? I have a 3x scope on my KE-7… what is meant by no suppression? That is a specialization that you can equip (suppress more and receive less suppression).
Sorry to hear of all your troubles. I suggest trying out a different kit when things get boring. There are myriad ways to play Battlefield.
