In practice, Aura is more like Ki than shielding in that the user can still suffer from debilitating blows and effects that focus less on brute force, and more on technique. For example, when Yang fought Neo, the small tyke easily took her out with precise, measured hits that depleted her Aura and knocked her out extremely quickly, when even mech suits with enough power to shatter concrete failed to do so, all because of technique and the opposing force in question. You're forgetting the fact that RWBY, including Yang, had already been fighting for some time beforehand, and did not get a full rest. Yang's Aura was not at 100%, not even close. So of course she wouldn't last as long.

Meanwhile, when she fought the Paladin, she had far more Aura at that moment, and had not fought anything beforehand.
