First off, only for hunters.
With any type of fear, it only fears up to 5 enemies, except for bosses. The Fel Overseers cast a fear. As a hunter, if you drop a snake trap prior to pulling, when they run over it and set it off, the snakes get feared instead of the party. Not exactly what Blizz had in mind I suspect.
Second, if you duel alot or arena alot, make a /kneel macro. Spam that a few times before actually dropping your trap and you're bound to make someone think they got away from your traps. Especially useful for watching rogues blow their COS early.![]()
