When I run with the crate, theres an exit camper like 1/5 times, and from that, i get killed like 1/4 of the time. Theres only so few great camping spots, when you learn them, you can scout them by sneaking & flanking because 99% of the time they are expecting you to run straight to the exit like headless chicken. The biggest secret is NOT TO run to the nearest exit, but carefully plan your exit route before you take the crate. Or you can just kill everyone nearby (signal detector comes very handy with this strategy) before even getting the crate (works best in duo lobbies with a friend).
