Leveling vs MSQ

[Niwashi]

This game is definitely focused around its main story, with most content being unlocked through the MSQ. For people who have time to do both, it can be a good pattern to advance one job with the leveling roulette while doing MSQ with another, but if you only have time for one or the other, MSQ generally ranks highest in priority.

You can still do the roulette occasionally when you get tired of questing and want a change of pace, but try to stay near enough to on-level in the story so that you can unlock level appropriate dungeons/trials.

I'd always suggest focusing on MSQ first on one class. Due to armory bonuses every other class will take less time to level afterwards. If you find yourself levelling ahead of the MSQ then skip the sidequests and save them for a different job. Roulettes are great but really the bonuses are built for people who have already done them as an incentive to rerun older content.
