I've been playing an Inquisitor.... Sith Sorcerer. Its good... good storyline and pretty OP overall. Get the PvP gear as you level once you hit 10 and fast track your Class Questline.. you'll level faster and can go up to 5 levels above what you're rated at. Keep the slotted/modable lightsaber you get around 20 too.. you can upgrade it later. Stacking crit works very well.
