I didn't think that I was by saying that trying to compare them to the people behind Avatar was being unfair to them. If it came across differently, maybe I could have worded it better, but that wasn't the intention.
What they did, was give her a sob story, something that has been done time and again to the point that it is practically a stereotype. And, interestingly, despite the choppiness, I think that volume 4 was handled quite well for the number of storylines that they were dealing with and the limited number of episodes that it was given, despite Ruby's continued interference in a fight that she was ill-equipped for, resulting in her just getting in the way. Personally, I think that it would have been better to split it over two volumes, or even one entire volume per character, but that would have probably drawn RWBY out longer than the bigwigs would have wanted it to for financial reasons. Volumes 5 was a different story though, possessing some characterization issues, some of which were carried over into volume 6, which also seemed to suffer from some consistency issues. Both of which can arise from long running series, but, to counter that, most writers document their characters, so that that doesn't happen.
