Look, its really simple. If you don't like the way activision has added all these extra things like perks and customising your weapons, then just don't even bother playing the game. Why take away any of the perks or weapons at all? It's what makes the game special in the first place, if these are taken away it just makes the game another point and click fps. Everything is there for added realism, so yeah if you really don't like the way CoD4 is the way it is, just stick to Counter Strike
