What aspects of the show should be explored deeper ?

What are the various aspects of RWBY whereas it is the lore or parts of it, character interactions and moments, emotional or comedic stuff or semblances and other powers and skills which you think should be explored and exploited further than they currently are in the show ?

I wish that there should be more about aura, its origins and the full extent of its abilities, with some characters such as Jaune, Ren and Arslan making formidable use of it.

I also wish to see more about the kingdoms' lore and culture, geopolitics, and relations with each other.

Also more interactions between characters who interact too little such as between members of RWBY and JNPR.
