Exp Level & MSQ

[Jeeqbit]

have to decide if I want to stick with my overleveled dragoon or level an alt class. I could also stop doing roulettes, that would help.

It's true that if you do anything other than the MSQ, at all, you will probably get overleveled. There is typically a gap of 1-3 levels at the end of ARR and each expansion that requires just a little bit of leveling via other means (such as FATEs and sidequests), but it's usually not that much.

From Endwalker onwards, they made the MSQ itself enough without sidequests.

You can do roulettes on other classes (since you can switch to them by changing weapon then saving a gearset). They are mostly intended for secondary classes.

Alternatively, you can just ignore that you are a higher level because it doesn't matter. The story will "sync you down" to the level of the MSQ for all duties, dungeons and trials. You virtually can't do content higher than the level of the MSQ in most cases due to the MSQ gating new areas and its associated content, so your "real" level is the level of the Main Scenario Quest, in most cases.
