new AIM system?

now this isn’t a 100 percent fact but I have been hearing this rumor about a new AIM system which is short for “Arsenal Improvisation Mechanics” and from what I heard it will let us customize our weapons IN combat.Now I don’t know about you but I’m pretty syched about this so I really hope its true. What do you guys think of this “Rumor”

As long as it isn’t default gameplay, I could care less if it happens.
