Plain Barbarian and Chanter (Skald) IE Howler class seems extremely powerful. Since you are in melee the chanter stun abilites are easy to target, and with the Skald crits can grant you phrases. I get phrase words reallly fast with carnage.
Same issue as this guy. Steam says the code was activated, but asks to click next to install, and there is no next button only finish, and it does nothing.
