Is there a way to purposely get lower dungeons in roulette?

The thing with newer jobs is that you start with a lot of buttons instantly so you have to sort them and get familiar with what is what.

Thats why you follow the questlines of them first! They have a instanced duty designed to teach you the mechanics of the class.

(tbh, i would prefer it if the class wouldnt be usable in dungeons before they at least finished that quest, just to promote people to learn the basics that way)

And also, after that duty, you should have enough information to start doing some duties with them. They are often not too complex at lvl 70.
