Those are still the best XP sources. If you're relying on Duty Finder rather than a regular group of friends to get into dungeons, though, you'll spend quite a bit of time waiting in queue for the dungeon runs. While waiting in queue, you can fill in with a combination of hunting log mobs, FATEs and perhaps a few levequests (plus regular sidequests as well if you haven't already used them up on previous classes).
