This is inspired by the discussion in the Naruto or Naruto Shippuden thread. Some of us have stated that the later parts of the manga/anime have introduced abilities that are too powerful and over the top. The hax powers of the Sharingan come to mind. So let's imagine how would the series look if it retained the "tone" in terms of power from Naruto and never went as crazy as in Shippuden. Now, some improvements and growth are of course necessary, but never to the extreme. For example, Sharingan can still have the Amaterasu, but would Susanoo be too much? Izanagi and Izanami could definitely be out (I think so, not sure).
