Your job change quests are considered KQs.

That's why when you die in your job change quests, you don't lose XP.

Yeah I know that. But he was saying that the job quests are the ONLY way to get the titles.......and that doesn't seem right considering the name of the Title itself =/

It's not the only way.

But the other way is iffy because you don't know the exact criteria involved.
