Maybe dust unlocked the first aura? We know that Pyrrha had to unlock Jaune's since he had no idea what it was. Perhaps people get their aura's unlocked in combat school to keep them alive, which is why Jaune didn't have his. Before anybody knew what aura was, they had no way of using it. When the found and used dust it may have unlocked people's auras for the first time, creating a double bonus. Elemental powers of dust, plus powerful people with auras.
