Are you guys seeing something I'm not? I've never really used assassin much, so I can't really say what the deal is with that perk. As for Stalker, I love it because I really don't like many of the other 3rd tier perks.
This is currently my favorite set up.
M4 with Extended Mags/Kick
I don't see the OP or whatever it is that people are complaining about, this goes for assassin as well? Someone please explain the experiences you've had because I clearly am not seeing what you guys are seeing.
