Try it, when you do go up against every twink warrior and rogue you can find. You will most likely be at the top of the charts, in deaths. Hunters are a ranged class. At 70 i can do a couple hundred dps in melee, however i am well over a thousand when i do what i am suposed to do, SHOOT! NOT HACK AWAY!
If you want to twink a melee class do a rogue, or warrior, hell, even a ret can be fun. Not a hunter though.
