Combat-wise, yeah, I guess so. The Bounty Hunter is more the equivalent of the Trooper in that regard. But I was aiming at their purpose, their personality. I see the Agent as having a certain amount of freedom, but having a fixed allegiance, instilled with a code true to the ideals of the Sith. However, I think those three classes can be seen as different types of Rogues. Not that it really matters what class they correspond to from a whole other universe.
