Does anyone use LMGs in this game? I tried using them but because of the maps I found them useless. Maps are too small with too many blind corners. LMGs don't seem to offer any real advantage over ARs or SMGs.
Yes - you need to unlock rapid fire for them to be worth using though, otherwise they're comparable to ARs at best, but with worse speed/ads/hipfire.
Their primary advantages are rapid fire and massive ammo capacity. This matters, because it's nearly impossible to down 3+ targets with an AR without going down yourself. You can do this all day long if you're positioned well with an LMG. They do have good penetration as well, but this is somewhat of a weak perk, as so much of the cover on these maps is thick as hell. In the places where it isn't, its a free bonus.
LMGs are hard to use though, just as they were in MW2. The slow movement speed means you need to know where to set up shop and when to move. The slow ADS means you need to be sighted
before that AR/SMG user comes around the corner, and pointing in the right direction.
For best results, get in a Ground War game with a non shit ping, set up shop somewhere and watch the killstreaks roll in. All of my longest streaks are with LMGs, not having to reload is a big deal.
Oh, and the M60 is the only automatic gun that can kill in two shots. The only other non snipers that can do that are the Type 95 (hurr, burst) and the Mk14 (semi auto). Close range only unfortunately, but nice in a pinch, if you get ambushed it tends to down your opponent really, really fast.
