what about editing your red dot,scope,acog.
i like a clean red dot cause thats more epic and fun. + better final killcam.
it's like you got emp'd in mw3.
and paint on your weapons. with pencil or something like that
and paint your chopper gunner,attack helicopter wouldn't that be epic? like those sharkteeth on your chopper like you always see on painted planes
or arrows pointing to the gunner.
instead of a grey chopper you got awesome stuff.
people have more fun+ people get better in painting= PROFIT

but there should be a option to put it off and on cause could get annoying.
and you should be able to see if people have it off or on so you know when to feel pro and stuff.
