I am loving this new loadout I've put together:
Enforcer, Damage Marker 1, Hawk Eyed 3, Scavenger 2, with 2 points left over that I can't decide what to put them into.
Damage Marker 1 marks people as you shoot them. So not only do you get the drop on an opponent, but you mark them for your team mates. Since I also run Hawk Eyed, the person glows for the whole team too. The act of not having to press R3 to mark the opponent is especially good for me, since R3 is also the camera, and a lot of the time I accidentally move the camera as I'm marking someone and by the time I've realigned it the person has ducked behind cover.
Hawk Eyed 3 makes the person glow instead of just having an arrow over their heads. This is especially helpful if the opponent does duck behind cover, as we can see if they are bandaging themselves, getting revived, reloading etc. Of course Hawk Eyed at Level 3 actually marks any opposing teammates who're stood near the guy you marked, so sometimes you are able to light-up the entire enemy team at once and all your team can see them.
Scavenger 2 makes me automatically pick-up the blue supplies that enemies drop when I down and execute them. I HATE having to pick these up manually, since sometimes they are thrown a fair way away from the downed body, even through walls so they're outside a building when you killed someone inside. It makes for stupid errors when you're hunting around for blue supplies, sometimes getting killed in teh process. Now I just run over to the dead body and I automatically pick them up. No need to even stop running.
All this not having to stop and mark, or stop and collect blue supplies, not having a massive recoil when shooting (revolver), and not having a gun with weak-ass damage (9mm pistol) allows me to be far more reactive, and I find I play much more aggressively.
My remaining 2 points I keep going back and forth on. Really anything works, I guess. At the moment I'm rocking SharpShooter 1. But if I had just two more loadout points I'd LOVE to put First Aid 2 on there so I could bandage my teamates.
