Honestly I think only Night Elves and perhaps the non-Forsaken races should be Hunters since the lore hints of a strong link with nature but the game starts with Dwarves being able to be Hunters which kinda throw it all by the window.
Inner Beast and other lore spells aside, Hunters in WoW are basically «dude who use ranged weapons» at this point, may as well open it to everybody.
