which "aces" aren't actually aces?

Chaeryeong and Ryujin and Yeji all 3 are amazing fantastic dancers! That is all they're good at, singing and rapping are very mediocre.

I'd add they have good stage presence.

Yeah, they're not aces but they're good at something at least.

Monday is truly an ace. One of the best vocalists in 4th gen, a really good dancer, can rap though not that great

Yeji... she's a strong dancer but her singing and rapping isn't super strong

Chaeyoung... she's a very strong rapper but lacks in both dancing and singing. Is she an ace because she's the only member who can do both of those at an okay job and excels in rap?
