Pandaria Best Spec for a lvl 10 player

[seriouslee]

So it's pretty straightforward what is the best 1st spec for the hunter?

[Fuly]

You can't go wrong with beast mastery, it's the easiest spec to level up. Put all your talent points in stamina, armor and whatever gives your pet more damage. Except for the Frenzy talent, only 4/5 points should be enough. 80% chance will proc most of the time given your pet's attack speed.
As for a pet you can take whatever you want for half of the leveling. I'd still recommend a Ravager since it has a stun, always useful. Especially if you get ganked by the other faction.
But once you hit the levels 40-45 you should take a Tenacity pet to learn Thunderstomp, you'll be able to take on packs of mobs with your pet using it and you just healing it and using volley.

I personaly like to be prepared for some PvP so I took a turn to Marksmanship after Intimidation to get Aimed shot and the bonus critical strike chance.
