Guys i think i found something. so this may be a coincidence but it lines up too perfect. the main things spider-man hints to is dancer, samurai,chemist and blue mage. OK so the collectors edition in game item reveals might be more than just randomly chosen things. Bartz is from 5 and 5 has all 4 of the said jobs to be able to use. Syldra was a summon that dealt wind aspected damage. Each job is assigned an elemental crystal. so not only does blue mage happen to be wind aspected,but the other 3 are all earth jobs with the only one being dragoon, the main focus of heavensward. its possible yoshida knew of the othero dismiss those jobs, and solidly confirm blue mage.
