My list is remarkably similar...
Guardian: Armorsmith, Weaponsmith
Necromaner: Jeweler, Artificer
Thief: Leatherworker, Huntsman
Elementalist: Tailor, Chef
Ranger: Lady Rhonwyn will max them all in time... Just because she can! She'll probably also (especially at the start) will gather most of the materials so the rest can craft the times she needs...
