The one perk I'm really excited for and worried for is actually the Elite perk Ping. Knowing where an enemy is after you kill somebody is REALLY gonna be helpful, so you won't get killed after killing someone and then getting shot in the back by one of his butt buddies.

Then there's the Stealth perk Takedown, making you technically invisible because when you kill somebody and no skull shows up, enemies will never know you are there.

Finally, I'd have to say the Resistance perk Painkiller, which means if you play your cards right, you are almost invincible. Capturing headquarters, or bomb sites, or Domination flags would be much easier, since you can regen health faster.
