I feel that something you should do is have Sagemode, Lightnight armor, and Kyuubi mode all drain stamina and magicka the longer they're used. Also, you should make jutsu's like kirin a little more expensive, because some of these are waaaaay to cheap for what they are. Also, try adding Akatsuki robes and all that ♥♥♥♥. I'm not forcing you to do this, just making some suggestions.
