I suppose they intend to follow XI's armor path for the jobs =p AF and Relic we're just recolors, but really noticeable recolors, then AF3 hit the scene and it was different stuff =p some of which was designed off of other FFs that job appeared in, instead of the first FF it appeared in.
Howver Kudos to the for making the Relic armor quite useful for all jobs in this game =p Dragoon relic was basically a joke in XI helm and body aside
