Well, think about it, if you get all your crafts up to 50, or whatever, and you get 1 battle class up to 50, there would be no quests left since you would have done them all on the first job, so for the other battle jobs, all you can do is grind fates or mindless grind dungeons to level up, 6 leves a day isn't enough to balance out the grind. Not everyone wants to keep grinding dungeons, especially those who are dps and have to wait 30+ mins for DF to popup, and there aren't many fate groups going. There are a lot of people that enjoy doing quests, leves is being a hub for quests. So, 6 leves will be gone in less than 30 min, then what? more dungeons and fate grinding. 7 other jobs just to grind from dungeons and fates is just plain boring. Game needs more quests for those other jobs grind. That's my concern once I finish getting all my crafts to 50, for I will be working on my other battle jobs.
