I'm also disappointed to see that they haven't added any new moves (from just using Naruto) or changed the animation of moves for previous characters. I was hoping to have the option of having (at the very least) one extra Jutsu or the Awakened forms having their own Ultimate Jutsu; similar to the Ultimate Ninja or (dare I say) Dragonball Z: BT series.
Characters and Jutsu aside, I do like the new Substitution Jutsu mechanic they added. I like the fact that opponents can no longer just rapidly tap the block buttons to teleport for what used to seem like an infinite amount of times. I also like how you can cancel combos and either perform a new string or dash back to confuse your opponent. Even though the combos in this series are simple compared to other Fighters, I still think it's cool to have some level of mix-up options available.
