I'm going to be sorcerer simply because a sith warrior can only be DPS or Tank, so i'll already use him as a tank, so i'd rather make my inquisitor a sorcerer so he can dps/heal that way I have all roles covered. I'm definitely going to try sith assassin tanking because force power is much, much cooler to manage and play with than rage. I feel the rage system is really clunky. To be honest I wouldn't make a sith warrior at all except the story is soooo awesome for them.
