Yeah, it depends a lot on each person. For example, what if instead of a Semblance, the characters just take the enemy by surprise before they use their Semblance to null their Aura? Or what if the character fights at range and it's too fast to get hit by the Semblance?

By the way, Ruby is 15 years old and it hasn't been confirmed that she uses Aura to be capable of wielding Crescent Rose. We don't know how much the characters depend on their Aura but if it was so easy to use Aura to move faster and hit stronger then Jaune should be capable of fighting at the same level but he can't not because he hasn't trained his Aura enough but simply because he hasn't trained his own physical abilities enough.

Aura Nullification Semblance would make for a great advantage but I'm sure we can think of something more awesome and harder to take down.
