Sure you can be Barbarian.
From the class desciption the Barbarian will focus either on knockbacks, crowd control or single Target DPS, depending on whether he uses 2-handed or dual wields. Its weakness is no magic (Obviously, as Conan HATES Magic) better hitpoints than other rogues, but lower hitpoints compared to the Fighter class. He also cannot use heavy armor.
Hes a bit like a WWII cruiser, designed to dish-out heavy punishment, but cannot take it.
Im gotta preorder the moment I recieve my new credit card.
Part II is out of the class definitions
