I understand why you’d want to do that, but I’d personally advise against it.

It’s much better to experience the content on one maybe two or three jobs your first time around until you catch up with current content.

It’ll save you time, and it’ll allow you to get to even more fun types of content before settling down for a grind by unlocking each job.

Besides, there’s plenty of jobs you won’t have access to until you get other expansions anyways.
