-Mostly older, above 20 members when the trend now is younger
-Let Yunjin debut even though she has left Kpop, returned to the US since no company debuted her
-Change the image of Chaewon/Sakura from cute/magical to edgy, strong performers
-Debut Garam despite her past
-Debut a professional ballerina with little idol training
-Choose risky songs (Fearless was called flat at first but is now a stable hit, Antifragile goes for reggaeton, which no group is doing)
-Hard dances while Kpop now is going for simple, Tiktok viral dances
