Money BF3 Investing Good?

I know this is a silly question, but I really want to know I will be investing my money good. Is it worth or no? I mean, how many anoying camping guy will there be? MW is like 60% Campers, 25% akimbo shotgun guy and 10% little kids and 5% normal guys like me who get killed like 20 times just for playing the game the right way. I am afraid this game could be the same. I don't know, I need real testimonies. BTW I will always be a Halo gamer.
