If all of your biases were in one group together just how well rounded would they be? My group would look like this Taeyeon - Main Vocalist Seulgi - Main Dancer, Lead Vocalist Rose - Main Vocalist, Lead Dancer Jihyo - Main Vocalist Sua - Rapper, Vocalist, Main Dancer Yuqi - Lead Dancer, Lead Vocalist A bit top heavy on the main vocalists... But overall quite well rounded with a decent mix of vocalists and dancers. Sua would be the only rapper of the group but that wouldn't be a concern as they would be a more vocal/dance focused group. Each member also has their own unique vocal colour so it wouldn't be too difficult to distinguish between the members when listening to the songs.
