I was thinking that maybe there should be more characters added. Adding some more characters, such as more TS characters, Akatsuki members and other characters from the latest of the anime/manga (this includes characters from the filler arcs in the anime). Any new character will do as long as their attacks were introduced enough where we can establish what attacks they have or if they only showed a couple attacks, where we could try to come up with as much of an accurate guess on what other attacks that person may have.
