Concentrating one's Aura at will to block more effectively, (if we assume that's what Ren did against the Taijitu and/or what Cinder and Amber did to block bullets) could probably be a somewhat-more advanced technique, something not easily done.

You are making some pretty significant assumptions on how Aura works. Each person has a supply of 100 aura units. Say a gunshot to the chest takes out 20, a person could take 5 gunshots to the chest before depleting their aura. Yang still has 100 aura even missing her arm. If it were to “concentrate” as you described it, does that mean she can take 6 shots to the chest before depleting? Why would losing a limb decrease the amount of damage the bullet imparts or increase her aura to compensate? She still has the same aura amount, or possible less aura if the fact that she is missing a limb causes it to decrease. And I would imagine aura is like "will", so losing her arm probably crushed her will and drained her aura. People like Ironwood or Mercury have massive wills, and thus are able to maintain their full aura.
