I can certainly understand the recent disgust towards Chu2, but she and every RAS member, still lack of deepening, growth and development as a characters, we have already seen part of their personalities, but it's that for now, that compared with the others 25 girls that a lot of them already had their own backstory and reasons for acting as they did before (Sayo, Chisato, Yukina, Misaki for example), we have seen them grow throughout the saga, and this eventally could happen with RAS girls.

They are still a very new band, and the only ones we've seen more of them are Rokka and Lay, and a little of Masking, with the chance of knowing much, MUCH more of them, I personally think that they have a lot of potential, as their songs that are really good and work so well as a group, I like them so much, but, for now, I simply can't compare them with the other ones in terms of characters, but that could change in the future, just give them time guys~

This could applied in certain perspective to Argonavis too.
