I guess BlizzCon will reveal the beautiful Queen Azshara, in the cinematic for the upcoming expansion.
Villain: Queen Azshara, Hero Class: Sea Witch, No New Races.
Now before you go on about the word "Witch", remind yourself that "Warlock" exist for both genders in the game already, and then that's out of the world - we continue.
Hero Class: Sea Witch
The Beginning of the Story
You were on a ship, but a storm came and took you under water. You are saved by Queen Azshara and her Naga followers. You are in an underwater city, you survived and you're training begins, they take you in, accept you.
But at some point, you turn on the ones that saved you, you somehow join the faction you belong to (Horde or Alliance).
Or: You in fact get attacked by some unknown forces and many of the Naga get's killed and Queen Azshara is there no longer. You are left alone, nowhere to go but home to Alliance or Orgrimmar.
Description of the Hero Class
A mystical hero that uses bow and magic. Use the power of ice and lightning.
First class that wields bow and can heal, also using mail for armor with intellect.
Resource is mana and a unique system underneath that again.
This just came to me in a light bubble.
I don't see why we would take on Kil'jaeden or someone else, before Queen Azshara.
She deserves her own expansion and can bring in a new Hero Class.
