How do you level more than 3 "Fighting" Classes if there are only 3 starting areas?

All you really need to do is get to 15 to unlock dungeons and then you're set.

The Hunting Log, a few FATEs here and there and maybe some Leves will get you there, no sweat. The 50% experience increase (that you can double with the 50% from rested experience) also makes a big difference for those first few levels.
