I've had situations when after putting VSAT up i see a guy spawning around the corner. I lock into position and prefire him behind corner from a reasonable distance. I get 1 hitmarker and he just instantly obliterates me with Remington while he's in the running animation. Black Ops 2 is the worst, bloated piece of crap i have ever played online.
And i haven't even mentioned plethora of other terrible design decitions cause frankly i don't give a damn anymore. It's over. They have to bank on 1 more DLC and this game goes into history.
