Job Jump Potion is Incomplete
As a warning to those who are planning to use the job jump potion, Squarenix forgot to mention that you do not get the AF gear for your job. If you want those pieces for glamour, you'll have to find the open world version of the gear. As far as I know, the jump potion does not affect the relic weapon quests, so if you want a relic weapon, like the curtana, for glamour you can still get them that way.
Edit: It just occurred to me that there is a chest containing an "AF 2" set at the conclusion of the level 60 job quest. I do not believe you can acquire this set any other way. This is probably an oversight on their part.
