What would you bring over from Classic?

You said you want professions to be “relevant” like they were in classic

They still craft heavily used consumables, can still make high end gear, and can still make enhancements like gliders

Engineering was a mandatory profession, it did that much, that doesn’t mean the profession is relevant, it means you have to have it otherwise you handicap yourself

So yea, professions going back to classic style would be a horrible change
