I do not have a "Main" I want to gear all jobs, change weekly gatings?

I just circumvent it by playing multiple characters.
That's how I main a Tank, DPS, and Healer at the same time.

And you get massively more inventory space for each role to boot. There's really scarcely any other way to go, so long as you can stand doing the MSQ again (and gleaning its burgeoning exp gains...).

But XIV was in large part sold on the idea of "all classes on one character"... and yet they're less alt-friendly in that form than almost any competing MMO. That's what doesn't make sense to me.
