Like Rexxar, what if BM spec was changed to melee? The weapons could be like 1H Axes/swords/fist/daggers(?) and they could still have their use of exotic pets, Imagine fighting along side your Devilsaur, Direhorn or even something as a Dwarf fighting with his bear.
It's abilties would obviously have the standard hack-n slash and hunter-traps and disengage but what if some abilties changed on the type of pet it had out or even buff the pet/player.
I would have suggested Dire Beast if it wasn't already in-game it could fit so well for BM-melee only.
