In all honesty I think it's fine the way it is, I didn't spend gil and tons of my time leveling all my crafts and gatherers to 50 to have to pick one of each that I want. I do however understand where your coming from and think that leveling these classes is far too easy, they need to remove the triple turn in hq bonus leves for a start. DoW and DoM don't have any triple turn in leves that I recall for more xp or gil. There are already too many crafters and gatherers saturating the market with goods and basically destroyed the economy because they're too easy too level.
