>Noob1 runs around the corner.
>Noob2 is in a tower with a loving stakeout with slugrounds.
He fires on Noob1 as he runs around the corner.
>Noob3 comes up and knifes Noob2 in the leg. Instant Kill.
>Noob2's Sluground rams Noob1 in the foot, providing instant kill.

Nerf that idea.
Maybe the slug round would be an instakill at close range, but maybe ~75 damage after that? Besides, if you got your foot blown off in a battle, you're dead anyway unless you can get help really quickly.
Also, on the knife: Sounds like they're serioulsy nerfing it in MW3, so probably no "knife instakill" anymore unless you do like a 3 second stab animation.
