BM hunter is a beastmaster, which informs abilities like kill command and the reliance on a pet to do damage for you, in addition to the ability to summon lots of pets at once.
A class fantasy is the ideal a spec is supposed to live up to, which is important since without it you wouldn't really have any idea what kind of abilities the spec is even supposed to have, like what happened before Outlaw rogue changed name from Combat rogue.
