SMN/WAR might be more of Dark Knight, considering SMN is DoT and Maur is 2h Axe.
DRG/MNK may be THF since DRG can jump and disappear (kind of like invisible/hide, I guess).
But for advanced job, it should require 2 jobs. Just like a job requires 2 classes. The question is if it's advanced job, what happened to the old job? Advanced job implies it's supposed to be better than normal job.
