Hmm if you get the Story potion I would assume that it automatically levels your current class to 60? And then all you really have to do is your job quests to 60. That'd be so weird if it didn't and just have all these quests unlocked but still have to do all the leveling work anyways?

And the job leveling potion would just go to alt jobs people plan on leveling?

Hmm idk I was planning n doing the story jump potion for one of my alts but If it doesn't also level their class then it seems pointless?
