How many characters can you level to 50 through quests?

[Hiroradius]

No, there aren't even enough quests to do 1 character. It's close, but in the higher levels, 45+ you will probably need to run fates, or dungeon grind a bit. Or do Battle leves.

Then when you go to your 2nd job, it will be dungeons, battle leves, and the occasional fate group., 3rd job and so on is the same

They didn't design the quest system like WoW, where each zone has numerous quests and you have multiple areas to quest level 20-25, 25-30, etc here up until level 15 you have 3 areas, then they merge and stay the same.. there won't be multiple level 30 areas for questing (fates on the other hand there are but usually only 1 zone is worthwhile while the other zones are not)

Best example I can give.. if you played final fantasy 12.. it's the same. There is enough quests to continue the story but no reason to ever go back for more. Pretty much everything you do, all side-quests, still somewhat deal with the main story, the fates have the technically real side-quests, in which a fate might need help to collect herbs for his sick father, or goblins have stolen someones cargo, things like that.
