Speculation and general delusions

I think everyone should have the same variations, just not necessarily for the same piece. One piece crafted (as part of a quest - you supply the materials.) Two pieces obtained as a reward for a storyline quest, as a gift from an NPC. Two pieces found in a treasure chest in a dungeon. XI's jobs ended up imbalanced, because newer jobs had gear crafted, and others just got it from quests or from treasure chests. (BLU was the worst! Crafted materials, one piece a day max, and you had to pay a frickin commission.)
