Yes, but thinking like this is "silly" bc if we start then we could say this about every other group who produces, songwriter which is not the point here. When talking about stage presence I can say that 3/4 are great.
They were 5 members, not 4, but 5: poor Seungri...
Yeah, the reason why I mentioned BB was not as much their stage presence, but more as an example how 1 person due to their unique or exceptional talents in a certain area can have fans credit the entire group for that particular talent, as if all members possess that particular talent on that level: for 2NE1 CL's stage presence, for BB GD's exceptional multi-talent.
