I tweeked my classes some. I have 2 sets of classes, sniping and runnin and gunnin. The first part of the class is set for damager which has stopping power pro and one man army pro. Once I get enough kills to get a attack vehicle, i switch to the 2nd part of the class which has One Man Army Pro and Danger Close Pro. That way when I call in my attack vehicle, the hits hurt more which will in turn help my killstreak raise before someone takes it out. Helps with getting nukes easier. I have it as Attack Chopper (7) Chopper Gunner (11) or AC130 (11) Just depends on the map and Tactical Nuke (25)
