Point taken, but I still say that making everything a sword is getting a little stale...I thought some of the innovations Kubo made in the past were cool, like Ganju's sand technique, or Byakuya's Senbonzakura...right now I'm just tired of regular sword-swinging and power blasts.
Though admittedly this new ability is interesting, there're lots of ways they could apply this to make it cool. It also looks like Kubo may be going for a technical angle rather than a simple power level angle for this arc, which is only a good thing. Only time will tell though...something about the pace still feels off though.
