It wasnt just the speed of the ads in cod4 which made it hard -
You rarely got a mw2 quickscope on cod4 without an acog, you had to hit the enemy with precision either in the head or chest other wise it was an immediate hit marker.
Where as in mw2 you can rape shot from 1000 yards hit them in the hand and get a kill from it..
"when i say mw2 quickscope i mean zooming in to a close up of the scope not actually looking through it so the equivilent of a no scope on cod4
