Monty said that Aura and Semblance will be explained later in the series, I'm sure that they will use Jaune again to do the job of the oblivious character who has no idea of the basics and makes the perfect excuse to explain us about it.

Jaune knows what aura is but he still has no idea about semblance, since Pyrrha is going to train him, she will teach him more about semblance and instruct him into finding his own.

For now, apart from Jaune, I don't think that any character has place in their skills department to improve. There has to be character development and more background arcs for the members of RWBY and JNPR, especially Nora and Ren who are still secondary characters. But in the sense of learning a few more tricks, it's hard to say the least since they are such badasses already. Of course, it doesn't mean that they can't be improved, I just don't know how but they will improve. If they remain using the same combos and abilities, at some point, it'll become boring.
