It makes the guns balanced and adds diversity to the weapon selection. If you didn't have the M16 3 round burst fire in COD4, why would you need the M4? IT expands the weapons supply and would make the game play slower due to changing the fire to suit each role needed. Trust me, its better off the way it is.
