@Anon above. Where does it say you HAVE to use them? I only use Hacker on one class, and Ghost on a sniper class. I use scavenger, or lightweight on all of my other classes. (Marathon, or ninja for tier 3) You don't generally need hacker to predict claymores. Just run, and gun tactically. Always assume a high traffic entrance/building has a claymore. Same for objectives. You have to think "What corner of this building would be best to camp in", and assume that a camper is there. Make good use of flashbangs, concussions, and even smoke grenades can expose campers. Even if a camper manages to kill you, you have the advantage. As you know exactly where he is, and can find some way of eliminating him.
