Which race to play as a World of Warcraft Hunter? That depends.

Do you group alot or go mostly solo?  If you group alot consider the Draenai and their Heroic Presence ability, which is a group “to hit” buff.

Do you PvP? Consider the Night Elf and it’s meld ability, which will let you hide (put your critter over there) and possibly lurk in wait for an ambush.

Are you just a solo leveler? Consider a Troll. It’s berserking ability might get you out of a jam every now and then.
