I'd like to suggest that a lot of ACTIVE Aura usage would be physically exhausting to the user.

With Ren, while he seems calm in most early scenes, he starts acting very exhausted, starting from his appearence in Ep. 8 and leading up to his collapse. While there might be an argument for it coming from other sources, I like to think this was due to using all that Aura power when fighting the  King Taijitu.

We also see that Pyrrha seems tired when she unlocks Jaune's Aura.

I think that the main limiting factor to Aura is that it isn't just difficult to use, but it also takes a lot of energy in doing so.

The main argument against this would probably how Yang uses her abilities, but I think it's possible most of her Aura usage is involuntary or controlled by emotions. There doesn't seem to be a lot of control there, just raw force.

Just thought I'd throw that out there.
