Just throw in the AT-4, make it's BULK absolutely unbareable, and since it's probably heavy, shouldn't it waver alot when aimed? And also, you should have to stand still to get the AT-4 out, stand still for 30sec to reload it, and stand still, and then crouch, then fire it, and no fireing from the hip. It should only get 2 rounds, and some of them should malfunction when arming [don't know how]. If someone where to spawn int a CQB map with it, it would be taken away automaticly, and sent to the load out screen where he/she must choose anther loudout.
