Yeah, the base being the generalized classes such as rogue and paladin being specialized by play method and preference. (Maybe ranks or titiles could be aquired[through no easy means] *Just a possibility* to improve certain stats or allow one to pull skills from another class that they wouldn't usually be able to (kind of like Materia in FF7, with only a limited number of active titles at any one time.))

 Will multiclassing be possible?
