Asura - The asura, who once ruled the caves and tunnels below Tyria, are an advanced race of small stature and large intellect. Having emerged from the depths, the asura aim to rule the surface world with their powerful golems and razor-sharp wit.
Charr - The conquerors of Ascalon, the charr are ferocious, warmongering creatures—the intractable foes of humanity. Now, as greater dangers threaten their conquests, the charr legions marshal their war machines to meet their enemies with deadly force.
Human - The regular citizens of Tyria, Cantha, and Elona
Norn - The norn are half-giant brawlers from the frigid northern lands who can shapeshift into mighty bestial forms. They've been driven from their homeland by a force beyond reckon, and now regroup among the lost dwarven ruins of the Shiverpeaks.
Sylvari - Not much is known of the sylvari, save that they are a race of sentient plant-beings, newly blossomed into the world. They are the youngest of the races, and are bound together by a common dream.
Personally I would be an Asura since there is nothing more humiliating than be pwned by a cute creature half your size.
My second choice would be the Sylvari since they seem like they would be powerful healers and Earth Magic users.....
So, what would you want to play as?
