Something I noticed about RWBY is that a few of the more illogical things in-universe just exist for plot reasons.
I only have a few examples.
1. Jaune not knowing what Aura is. Out of Universe/Narrative-wise, Jaune fills the role of the “average” guy, like the audience, who doesn’t know this world and needs to have someone exposit to him, and therefore the audience, how this world works. BUT, this also makes you wonder from an in-universe stance, “How could he want to be a Huntsman if he doesn’t now what Aura is? Why doesn’t Pyrrha find this suspicious? If She wasn’t feeling nice then Jaune would’ve gotten splat from being launched off the cliff.” And even then it makes no sense, because this is the ONLY time Jaune is used as the “Guy who knows nothing so we need another character to exposit for him”. Every other time world building has happened it was with an entirely other group of people.
2. Th CCT Tower. Everyone in the FNDM agrees that the whole “If one tower goes down all of them don’t work” shit is stupid. Why the fuck would you design a communications system like that? But out of Universe they needed to set that up (via the World of Remnant on it) so the bad guys could do their big evil plan and divide the world. If everyone could communicate after the Fall of beacon then they would’ve been able to talk things out and explain shit. But keeping everyone radio silent with each other allows for fear and suspicions to rise (This of course is me pulling stuff out of my ass because this wasn’t stated in any RWBY canon but it seems like that is what they are implying). Also the fact that this happened in VALE which, according to the World of Remnants on the individual Kingdoms, seems to be the “BEST” Kingdom out of them all (Not a god-forsaken desert, no massive criminal underground, and not in the freezing tundra) I can’t help but feel like this was deliberate
3. The Maidens. The way the maiden powers work is that upon death, the power will transfer to whoever was last in that Maiden’s thoughts, unless she is too old or it is a guy, then it is random. After seeing Ozpin’s big flashback we saw the four daughters and immediately assumed that he made the Maidens to be replacement goldfish, as we had already assumed he was connected to the old wizard in the story. This rule allows the villains to obtain the Maiden power and do evil shit, but then you ask “Why would Oz make it THAT easy for evil people to gain this power? Seems like a massive lack of foresight” Also, WHY make the Maidens the keys to the Vaults holding the relics? Did he ever plan on using them himself? Why not just make no key so Salem NEVER has the opportunity to get her hand son them? He should’ve given the Maiden powers the “Transfers into a similar soul” rule like his own reincarnation, minus bringing the past soul along with the power. That keeps the power out of enemy hands. But it has the current rule so people like Cinder and Raven can get BS magic.
Just because something sounds cool doesn’t mean you should put it in. ESPECIALLY if it makes no sense in-universe.
