She's definitely not better than things like CT Rachel/Arakune or CS1 DLC. Probably not even better than CS1 Litchi. Also still have to be a good player to beat other good players with her. It's still Tsujikawa and Matoi regardless of whether they are playing Koko or Tao. Ya, much of the cast probably goes 3-7 with her, but I disagree that that eliminates them from tournies. Especially in America where the play level is significantly lower. (Though I guess that runs both ways.)
