Ok, so, about Raven vs JNPR:

I think it really depends on when it would have happened, how and why Raven would do it.

Maybe Raven didn't want JNPR in the tournament because she knew the Brotherhood was evaluating Pyrrha as a candidate to transfer Amber's powers, so she intended to either incapacitate or kill Pyrrha. Why? Maybe she is against the aura transfer/ wants the powers for herself/ really hates the Brotherhood/ dislikes Ironwood even more than Qrow/ is working with Salem/ wanted to send a message.

Maybe JNPR weren't even supposed to be in the kingdom. Maybe the scene was meant to take place at that village they didn't get to visit in V2, and Raven didn't want them there for some reason.

About Pyrrha's death.

Maybe the idea was for Pyrrha to get half of the powers and battle Cinder with them. Cinder defeat her and get the full powers, instead of it being a full powered Maiden vs a normal (prodigy) student.

As for Jaune causing Pyrrha's death, his semblance seems to have some form of shield/reflective ability. Maybe it was meant to unlock untimely, reflecting something in the wrong direction and directly or indirectly resulting in Pyrrha's death.
