This would be kind of bland, as you would already know the outcome of everything you do. However, this does give me an idea for a sort of new class. Say you had a guy that was sort of a jack-of-all-trades, that would be hired by anyone, (sort of like a mix between the smuggler and bh), and it would have no advanced class, just three disciplines- heal, tank, damage. The three disciplines would have slightly different storylines with the healer helping people, the damage guy acting as a mercenary, and the tank doing sort of a bit of each. With each discipline, there would be weapons skills- basically your essential weapon and a stealth skill for healers, a weapon and shield for tank, and two weapons for damage.
