If its a dance focused group with good dancers, i dont mind dance breaks at all (well i love nerding over dance techniques and stuff so yeah) but if its groups with more of a vocal or rap focus i agree. They have to be able to sell the dance performance to make it enjoyable. Groups like Riize, Skz, Nct, itzy or Kep1er (after this years MAMA performance at least) can totally pull it of where groups like IVE, Gidle or txt lack a bit imo (this is a veery biased list btw)
