FYI, Lynata suggested I check out the Desperado role since it's Role Ability is reminiscent of the Seraphim's table-top Hit and Run rule.
Looking at the Desperado, I am sold on it (I get Finesse!), and will be switching over my character sheet as soon as I can (hopefully tonight).
The Desperado is one of my favorite classes, actually. I like that it offers a mix of survival, shooting and social skills, and the role ability is surprisingly useful. It would be a god fit for a Seraphim who wanted some social ability in addition to combat skills.
