Im sorry but what is the point of you ?

hunter seems to be a very popular class on my realm (20% of teh characters on my server are hunters)
and for the life of me i cant figure out why the hell i would want you in a 5 man or karazhan.
your damage is appauling your pet is an annyoing little bastarad and your traps are unreliable at best.
so why would i take you? theres got to be some reason for the existance of your class then to be really #!**ing annoying at 19 pvp.
