Why no speculation on Jobs for crafting classes?

Have you ever been to a doctor?

See you have your general doctor that assesses how you're doing, then you have your specialized doctors that tell you the specifics (there's a doctor position for almost every single organ inside the human body, the most specialized such as a heart doctor or a head doctor, they're specialized because they are doctors of something specific, that they don't work any other part; same thing here).

I'm not disagreeing with the sentiments of more crafting classes as I am about your terminology.

Except doctors are all trained in the basics of their craft. Every doctor had to disect a dead body. Every doctor had to learn how to deliver a baby, etc. They may have specialized afterwards, but they are still capable of performing their basic duties.
