Smuggler - "you'll get the choice of pursuing the stealthy line by becoming a Scoundrel, or take a more direct approach to combat with the dual-wielding, sniping Gunslinger. Intriguingly, the Gunslinger also comes with the 'Smooth Talker' trait, which gives you additional dialogue options."

Jedi Consular - "can focus more on their passive Force abilities(healing) or move to building upon Force stun and telekinetic powers to deliver damage and to support melee DPS and tank classes with mez effects."

Sith Inquisitor - "Once the career path option opens op, you can move into a Darth Maul-type character with a lightsabre staff, plying your trade as a lightly armoured but extremely acrobatic warrior. Alternatively the Sith Inquisitor can remain at a distance, focusing on the ever-deadlier DPS Force lightning abilities."

Sith Warrior - from the official site. "Juggernaut - Sith who train in the stalwart arts of the Juggernaut boast unrivaled stamina in battle. Through diligence and clarity, the Juggernaut shapes the Force to his will to become nearly invulnerable. Damage that would destroy others is shrugged off, and futility fills the Juggernaut's foes with doubt and despair." (aka tank)

"Marauder - Wielding two sabers and unmatched aggression, Sith trained as Marauders slice through enemy ranks, dealing death with merciless efficiency. Able to intuit precisely how to attack in order to maximize every strike, their adversaries become victims in the blink of an eye." (aka dps)
