I would swap out silencer for extended mags. Gun just "feels" stronger without it, and you benifit more from the extra ammo.
If you are camping with amplify and have a headset there is no need for ready up and QuickDraw, you should hear them all coming and already have your sights up. Personally I would also get rid of focus, it's just not needed in this game, especially since you "should" be getting a jump on everyone.
Next, get rid of the IED, you do not want to give away your position to sitrep users.
So so I that would give you an extra 6 points.
2 - dead silence
2- blast shield.
2 - scavenger
trinity rockets - heli - gryphon
A few things I gather from this:
either Remington/Honey/Mtar with Blue Dot
or LMG thermal
optimal KS seem to be Dog/Bridge/ Gryphon/helo/Loki
I guess blue dot is better than red dot? I've always though Red dot seemed a bit sharper or something I'll try out the blue.
My best KD overall is with m27 myself but I find it a little slow when going against tougher competition, so If I was stuck on a desert island I'd prob take an AR over it, Remington or AK-12.
I was a flak jacket junkie in all other CODs, but haven't used blast shield much on here. Nor the double IEDs, figured hardline is better over double lethal since 1 IED equates to 1 less kill for hardline plus assist bonus.
I can see points about amplify conflicting with quickdraw and ready up, I guess I've looked at it more as a safety bonus instead of relying on amplify to no longer need QD and Ready Up entirely, but I could try getting rid of those 4 points for either
INCOG/off the grid then takedown/resilience
Blast Shield/Dead Silence/Blind Eye
M27 with Tracker and Muzzle Brake.
With Support Killstreaks such as Satcom, Ballistic Vests. Use anything else you can put down/up quickly. No Jug or Heli Scout. This class is if you are a "camper". I average a 3.3 K/D with this class in OBJ gamemodes.
As for my RNG class that I average a 3.0 K/D in TDM is this:
K7 with Grip and Extended Mags
Again with Support Killstreaks such as Satcom, and Ballistic Vests, but now that I am running a SMG, you want to use Ammo Crate as the third. You can see where enemies are. You can resupply ammo if you go on a long tear. And you can protect yourself from getting outgunned with temporary extra health.
