I had the same attitude as the OP until I played with 3 of my friends. I thought it was a boring game-type where you pray for the best gun from the box, and run in a circle for 20 hours on end so you can place high on the ranking boards.
However, I found it can be with friends, seeing how far you can get with whatever weapon the box throws at you, using different perk combos and the like.
It's a welcome break from the frustration of multiplayer, where connection issues and unbalanced guns are rife.
