Is it lack of stand out members?
Disagree. They all stand out.
Goeun and Swan have some of the more unique, strong vocals from this gen. People compliment the both of them on this.
Dosie and Jieun are great dancers.
Chaein and Ireh are also talented.
Yuki is pretty good at rapping and also charismatic. I think she has a lot of potential.
Not only that, but the members actively participate in making their music, which is neat and yeah they are very talented.
I'd argue that this is the group with some of the most potential. From all the members. They are incredibly charismatic on stage. And have qualities that make them stand out from each other.
I have heard some people site their visuals as being a reason for people not checking them out. Which I think can be true. Yes, they are all very pretty, but they also aren't all pretty in a conventional way if you feel me. Not sure if they fit the same tastes as other popular 4th gen groups so that's unfortunate... I don't know if that's the full reason either. I do feel like in a general sense with how oversaturated the field is, it's just harder to really get people to notice you even if you do have talent and unique qualities too. I hope things change though either way. I hope people can take notice of their unique qualities soon.
