Search the mechanics and classes section. You will find your answer.

What are the best dps classes?

Warri, Mage and Rogue are the best dps. But people expect you to play tank if you play warri. Your maximum dps depends on which class you can play good.

So hunter isn't on the list?0.o

The best dps class when the server releases is Rogue,
and it will remain the best melee dps for a long time.

Warrior isnt really good dps before naxx because of gear dependency
Mages isnt really good dps before AQ do to mob fire resistance
Warlock isnt good dps before BWL do to debuff limit.
Hunters has the lowest dps of all the dps classes. But does better dps than hybrids/healers.

So is better to play a rogue than a warrior for melee.That's sad
