Most of them have better than mediocre vocals and some having great ones.
That being said they have good vocals considering they are dancing at the same time which is a strength.
I don't think they are lacking in dance as seen with Nicole's dance off with the others at an Inkigayo a while ago I believe...
But talking of Nicole, I feel her rapping is not really powerful, energetic and not nearly as charasmatic as it should be. If you look at (not bashing btw) CL's rapping and Nicole's, they are quite different in strength. Nicole CAN rap but could definitely work on adding power into her rapping ><'
NO BASHING BTW OMG I LOVE HER SO DW LOL
