I feel like the aura shield that Cinder used to block the bullets isn't some super rare technique, though. Ren used an aura shield to stop the King Taijitu.

And hell, dust is activated by aura, and you have to have a level of discipline when using dust in its raw form (like Cinder does), so maybe you have to train a little more in utilizing aura in order to properly control raw dust. Therefore, it's not unreasonable for some strange masked bandit who's using raw dust to be able to make aura shields.
