The pending question is: "what are the essentials for Performer/Professional/Sage, and how do I make a symmetrical split between the four roles over levels 4, 10 and 16" (because those are the levels that I have room to maneuver with if I'm to maintain a clean class design).
That's a tall order... I wish you good luck haha. All I can think of is:

Performer - social skills, Perform, charm effects

Sage - Knowledge skills, divination effects
