NO! Keep the game simple, like cod4, Im fed up with all these killstreaks! Killstreaks DO NOT make your stats legit, Any noob can camp in the corner, and earn an AC130 or gain a Nuke, within a few minutes, when all they did in the game was use there weapon to gain there killstreak.
Meaning, the person who takes FPS for real, will be outtaken by some noob who has a higher KD/R than, because he keeps gaining Nukes, and AC130.
Call of Duty should be kept original, Its about YOU and YOUR GUN.
Not YOU and YOUR KILLSTREAKS, you might aswell call it, "Call for Killstreaks: MW3"
