Ruby just generally sucks as a character. She has some motivations, but they aren't terribly interesting. I think they're trying to present her as a relatable figure, but all she really wants to do is fight, making it hard for anyone to understand what really drives her. It doesn't help that we don't get any real insights into her thought-process, and we have yet to see her own interpretation of her upraising.

In addition, we don't see all that much of her. She can sometimes feel forgotten about in her own show (think Bilbo in the last Hobbit movie), and what we have seen is poorly-developed. Sure, she had a decent amount of screen-time in Volume 2, but she still feels really empty.

What we're left with is a weird pastiche of "badass" and goofball (goofball in Miles and Kerry's OWN WORDS). She isn't socially awkward anymore. She isn't a solitary figure like Blake is. She isn't as good at fighting as she was in the Red Trailer (unless that was intended as a flash-forward, which, without wanting to cast aspersions, I really doubt). She's just nothing.
