Job Quests

[Felis]

Is there any info that says we will be a lvl 50 WHM or whatever when we equip the "job stones"? I was think one would be a lvl 50 CNJ equip a WHM "job stone" and start lvling a lvl 1 WHM.

Jobs don't have a own level. They have the same level as the class. If you unlock it with 30 you get a job 30. If you unlock it with 50 you got a job 50.
