I was disappointed with the name Sage so Viper is a bit disappointing as well. My bid would have been for something like "Twin-Fang". Generally the same but more of a nod to the dual blades and less a poisonous snake.

However, having said that I assume the naming is due to it being a New World job and therefore being named by the tribes of the new world.

I would expect the new caster job to be similarly "Animal aspect" named, perhaps "Turtle"?
