That's why she kept jumping into the fight despite most likely having no Aura left and said "I won't stand by and watch someone get hurt!"

Bottling up your emotions means that you sometimes don't have a level head, and those emotions can flare up. When Tyrian cut Qrow, Ruby had a temporary flare of emotion that caused her to lash out without really thinking about it. And that's dangerous. So, if we're keeping track then, Ruby's weaknesses include Low Physical Prowess, Lack of Experience, Inability to properly handle Emotions, and if the fight with Tyrian is an indication, low Aura Reserves (Or Each hit of his was hard enough that it managed to drop it by about 15%) cause I think she was only hit by him 7 times before her aura broke, most of which being basic kicks and impact blows rather than cuts.
