Your best bet if you are gonna be in groups/raids and want max dps is:
Beast Mastery:
[5/5] Aspect of the Hawk

Marksmanship:
[5/5] Improved Concussive Shot
[5/5] Improved Hunter's Mark
[5/5] Lethal Shots
[1/1] Aimed Shot
[5/5] Improved Serpent Sting
[1/1] Scatter Shot
[5/5] Ranged Weapon Specialization
[1/5] Hawk Eye

That should be you for lvl 42. Each level, you gain, add points to Hawk Eye until you reach 30 points in Marks, then 1 point for Aura and continue for Hawk eye.

This should leave you with 5 points at lvl 6.
You can choose between Barrage [/2] Improved Scorpid [/3] or Improved Arcane [/5]

I put my 5 in Improved Arcane but kind of wished I put 3 in there and 2 in Barrage.
