if you have an RP focus, not sure what jobs you do behind the scenes really matters. I understand that coming from WoW you are used to having 50 alts or so, but little need for that here. you can easily have a main job that is based on your character and the rest are OC.

trying to make the max number of alts here just seems more of a waste unless you need to have different races as well to fill out your mental landscape. in the end though, its all personal taste, its a game.... do what you want, not sure why you need guidance for what is ultimately personal preference on how YOU enjoy the game.
