You've very quick due to stock/lightweight & your sensitivity.
If I play very clever straight off, I usually get a VSAT within the first minute or two. I got 3 VSATS on HC DOM yesterday, while playing objective, put I'll need to now find a way to add in trophy systems instead.
Perk 2 is essentially pointless on Hardcore, you don't need it. If you're worried about ammo, get into a habit of picking up the first guys gun who you kill so you have a backup.
Your choice of one equipment. Usually C4 or Trophy System for me.
I think Ghost is worthless when a FHJ will shoot down UAVs and you get points for doing it, reduce the enemy advantage and help protect your team. Only use of Ghost is on bad people who are only looking at the radar when they get a UAV up.
Sometimes I will drop Cold Blooded and the equipment to put Primary Gunfighter on with Quickdraw Handle, but only if I am getting rushed a lot by SMG people and not able to deal with it due to some lag or whatever. Normally not necessary as I play at a fairly long range and usually just counter snipe people and roam around long lines of sight.
