A bunch of people posted ideas on this discussion of mine
The setup I like
L86 LSW w/ 2 attachments, grip and thermal scope,
Secondary usually stinger
Recon (pro preferable)
Hardline for assault class and quickdraw or assassin for support
I like trophy to stop preds but it's kind of counterintuitive to not have flashes with recon
UAV pred AGM for assault
Using the PKP for now to get an extra easy 10k from weapon proficiency, it's okay but I'll have to see what it's like with grip and thermal before comparing it to the LSW.
I have them all gold and In my opinion the pkp or Mk46 are the best my classes are
Pkp Attachments Grip/Red dot
RPG (love rpging)
Portable radar or flashes depending how you play
Assualt: pred Ah-6 Pave low
same with the MK46 but its pretty good with grip and silencer, if u want to use assasin
I have been using all of the LMG's this prestige to change things up and find which ones I prefer. I have 2 favorites... the MG36 with grip and speed proficiency, and the MK46 with a silencer and speed (or kick).
With either class I use blind eye for perk 1, quickdraw for perk 2, and sit rep for perk 3. The speed proficiency lets you move at a speed comparable to carrying an assault rifle, and the quickdraw lets you bring it up like an assault rifle. The advantage over most assault rifles is the clip size and the minimal kick if you burst fire and the power at ranges. I would still say in general assault rifles are nice, but I like the fact you dont have to reload until you have like 6 or 7 kills already. The reload rate on the MG36 is very nice, so I would favor that over the MK46.
My usual LMG setup:
Any LMG w/Dot Sight, Grip, or Suppressor. Speed Proficiency.
Claymore or C4
This kind of class has three purposes.
1. Run n Gun, due to my enhanced movement and ADS speed
2. Going prone to suppress areas, with a Claymore and Trophy System to protect me. (or C4 if I want to be more offensive)
3. Anti-Air, because LMGs with Blind Eye Pro, is a nasty combination (the Stinger is there just in case I need to reserve ammo)
Also, All of the LMGs in my profile, are level 30. And my favorite one, would have to be the MK46.
I play with the M60E4 with the Attachments proficiency using a red dot sight and grip.
Stinger, semtex, two flash grenades.
Sleight of Hand
I use a Support class of Advanced UAV, Stealth Bomber and EMP.
Contrary to most users I thoroughy enjoy using LMGs (particularly the M60, which I loved in CoD4 and used a prestige point to unlock straight away in MW3) and I usually clock a 2:1 K/D ratio when using them.
