Why not an alt instead of moving jobs?

Levelling is super easy, you don't need the MSQ to do it.
It's never been easier, in fact. Exp rains down on you.

I went from 30 DRK to 50 DRK in a little over a week just doing the solosquad dungeons, for example. A single run of the highest one available to you up to level 50 will net slightly more than one full level's worth of xp. This is only something you can do on a character who has already completed a bunch of content on another job. Just one of many ways that exp is far faster with am experienced character than with an alt.
