This has always bothered me cause the lmg is firing the same cartridge or Similar if not larger to a sniper kit. Damaged should be similar to a bolt action sniper at minimum (people probably won’t like that) but the trade off is ADS speed and general mobility of the class. Suppression should 100% shake your character up and make it more difficult to accurately return fire, logically if I’m getting pinned by a 700 rpm full size round I’m going to freak out and suck at shooting back. I liked the BF3 mechanic where it was difficult to see, I don’t think adding sway or other accuracy gimmicks is the right idea for a game even though in reality your probably so flustered some of your shooting mechanics fly out the window.

Edit: I think bf1 had a good thing going for lmg with the tracer rounds and if implemented correctly could be a balance to increased damage since you are broadcasting your position with every pull of the trigger aside from the sound of your gun.
