Agreed. Ive been a victim of being killed at an exit but what's the difference between camping exits and camping crates or objectives? All are legitimate strategies. The object of the game is to SURVIVE the match and get out with your weapons and loot. You have to play smart and use any advantage you can get.
If you get killed by an exit, great. Now you know where people can camp and you can look out for them next time. That camping player just taught you a valuable lesson. 😉
