I just can't imagine any other members pulling off solo stages with live vocals than these two, Eunbi and possibly Chaeyeon. You can't lipsync at concerts and make it as a solo. Chaewon just seems to fit perfectly as a group member even if she might have the vocal ability.
Chaeyeons solo debut will be interesting, I'm worried about her company since they've clearly dropped the ball already by taking this long. I'm also not sure how popular she actually is in Korea, I-fans obviously love her so there should be decent album sales.
I worry a bit for Eunbi fading into obscurity, she is underrated and Glitch was a banger 
She is still killing it compared to your avg. female soloist and I'm sure Woollim are more than happy with how it's going since she probably outsells any other Woollim artist at the moment. It's hard to not compare to the other 2 IZ*ONE solos though..
