What I would really like to see when want a new character. 
Just replace Frostborn Dwarf by Vrykul, Leper Gnome by Mogu and Vrykul by Saberon and my dream will be complete. 
Broken, Ethereal, Vrykul, Furbolg, Mogu and Ankoan/Jinyu for the Alliance. 
Ogre, Taunka, Saberon, Forest Troll, Gilgoblin and Sethrak for the Horde.
Hanarin and Tuskarr (with eventually Mogu and Vrykul) as neutral race.
Please blizz, make it happens.
Ogres for the Horde.
