hunters really had only 2 class "fantasies": MM and BM. If anything MM should use a pet for utility, and "Lonely Wolf" could get a name change and still increase hunters own damage but his pet should then get a 99% damage done reduction. This way it would not be a problem for people that don't like "pets doing damage" -they could just keep their pet idle in most combat situations while still preserving that "hunting with pet and bow/gun" feeling. BM feels like its a spec that could be both ranged and melee. Playstyle would change based on wep equipped or some kind of "stance". For instance Cobra Shot could become Cobra Strike, Disengage > Harpoon Toss. All same mechanics just a weapon type would determine if its melee or ranged. Ranged could deal tiny bit less damage perhaps to compensate for melee version having worse uptime.
Alas Artifacts happened to its lost case for this expansion.
Survival tree was invented only as "supplement" spec anyway. It never had any solid "backstory" or own identity. When blizzard made specialization trees into "solid talent tree" that made it feel like MM but with DoT damage rather than direct with few perks around improved traps. Not a very solid idea to justify making it a spec as... well... imagine a hunter (be it irl or fantasy) not using traps, camouflage or other hunter tools.
