Race specific classes for future expansions

Hear me out,

Since we are getting cross faction and Dracthyr with the evoker class. I think its time for future expansions that we should be getting earlier races with a specific classes.

I know its going to be pretty tough for the wow team to keep the game balance each time they add a new class in the mix, but how awesome would it be to see a night elf warden class, a blood elf spell breaker or troll shadow hunter. We can even make a different look for draenei seers as the lost ones and undead nerubians.

What are other races with specific classes would you like to see?
