How often do you change jobs when you play?

I main SMN and have it at 90 as I'm caught up with the MSQ. Since SCH shares a base class with SMN, I have that at 90 as well, though I haven't used it in a while so if I were to pick it back up I'd probably do badly. While I was still on the free trial and I reached the level cap in SMN midway through the main scenario of Heavensward I started leveling DRK, which I recently got to 90 after grinding for a while. The only other job I have at 90 right now is RPR, and I'm currently trying to level DNC so I have at least one job in each role. I usually just play SMN outside of leveling since it's what I'm the most used to but sometimes I'll switch to a different job if a situation calls for it, like if I'm trying to solo an unsynced boss from an earlier expansion and I'm only able to do it as a tank. As for why I decide to level jobs other than my main in the first place, I find it satisfying and it gives me an excuse to check out side content that I normally wouldn't with my main.

I level everything, and I try to keep one of each role equally geared (as well as, obviously, keeping up with how to play that job competently). In ShB it was GNB, DNC and SCH. In EW it's GNB, DNC and SGE.

Pretty often these days, will keep changing jobs till i get atleast a 99 on every single job. Currently workinh on SGE.

Outside raiding, pretty much anything on the go.

Thanks, guys - how do I unlock or find Palace of the Dead?

Not often enough I've gotten into a rut mostly of playing WHM and RDM most of the time.

The trick is to level your favorite jobs concurrently when you can. With the XP given for completing the MSQ + side quests, one can easily get to at least level 30 or so on three separate jobs these days. When working with alternate avatars, that generally ends up being Summoner, Bard and Paladin, which encompasses each member of the Sacred Triad, since leveling Arcanist leads to both Summoner and Scholar. Since just killing hunt mobs gets so much XP, one frequently outlevels the content on a single job, by as much as 15 levels. Spreading things out makes it easy to substitute for a different "playstyle of the day" when leveling.

Oddly enough, the MSQ + side quests (+ FATEs) + et cetera also work in a similar fashion for level 80 to 90. Getting to level 90 on one job via MSQ + dungeons + occasional FATEs plus getting to level 87 on a second job via side quests + FATEs plus getting to level 82 on a third job via Hunts + FATEs (plus Tome hunts now they're active again) still makes leveling to max level on multiple jobs easy.
