I was actually thinking Ninja should be a smaller specialty of the Thief-job, and likewise, Samurai a specialization of the Berserker-job. I don't like the idea of Red/Blue/Black/White Mages only because they are all covered by the Armory system, so the jobs should focus on the actual cast, not the spell-pool. I think the jobs themselves should be rather broad, even if they contain specializations. Or even just have oriental weapon options for the Thief and Berserker for the same real effect
