Hello, I've started world of warcraft and I'm a level 45 hunter.

I've got a dual talent spec which lets me swap between the talent trees, (you'd know this sorry)
(just say marksmanship, beast mastery, or survival)

I need to be good at PVP, so I need a tree which is PVP base, what one for this
And I also need to level up Fast, and I do alot of dungeons..What tree for this?

I was thinking Marksmanship for pvp, and survival for the levelingup/ungeons, as it's group attacks.

What you guys think?
