Not always the case though man, I mostly play HC game modes so no radar, I use it and SitRep to hunt down the other team and the only time you'll find me sitting in a corner is if I'm pouring a mid-game beer!
I use it and i run and gun. While i am running i like to hear where they are coming from that way i can be the first one on target. if you are camping you dont need this perk imo.
what really needs a buff is the throwing knife. it should be a boomerang and come back to you after throwing also it should go threw all walls and one shot everyone when thrown.
