Am I doing it wrong?

[Odett]

If you've exhausted your side quests with your main, job then you can do the following to gain experience for new jobs:

-Daily Leveling Roulette
-Daily Guildhest Roulette
-FATEs
-Level-appropriate dungeons
-Levequests
-Hunting logs

Have you unlocked the Challenge log? If not, you can head over to Limsa Lominsa Upper Decks and take the quest "Rising to the Challenge". Your challenge logs resets weekly and it's a great way to earn bonus experience by doing what you're already doing. Don't forget exp food and such. It's small, but it can add up and it's dirt cheap, so why not? There's really no "wrong" way to level up. Just do whatever you're having the most fun with, and vary things up a bit so you don't burn out. If you want to level the most efficiently, just never sit around. Like, if you're DPS and waiting for a queue, it's a good idea to do levequests or FATEs or your hunting log while you're waiting to get inside a dungeon.
