You could really say this for any character, though Ren's a very good exampel of it.

Ruby has literally never gotten developed until people have died, and never learns from whatever experiences she's had, just doing ass-pulling techniques, and when it doesn't work, she needs someone else or chance to save herself.

Weiss is one of the better developed characters, so nothign to really say there, even if Volume 3 Weiss' development was a bit forced and she otherwise remained semi-stagnant.

Blake, nothing to say there, since she's basically a darker, angstier version of Weiss.

Yang, I agree...up until mid-Volume 2, and definitely up until Volume 3, she was a background character and nothing more.

Jaune, he's had off and on development so nothing to say there.

Nora, like you said, is literally now the most background character of the main group. Evident through her amoutn of screentime, which is quite lacking, even in this recent Volume, where she got the least of RNJR's time (where she or a part of her was visible on screen), the most minimum of dialogue, and remaiend pretty stagnant as character, in contrast to Ren, who changed a lot and got the most screentiem of all of RNJR (even before Ruby & Jaune!).
