im playing hardcore only (Real Ops), i like that the best, no red glow, ^^^ yea spec ops C perk, lol. same here , you hear it then have to move. i found it good for throwing grenades at people. i changed FOV to 120, really annoying, there are 2 FOV settings only 1 Available in consol... hope they address this, it will be hard for them to patch cause its integrated in a strange way.
