well i was wondering how sasuke can be so good now as to not use handseals to do his chidori, has hasnt done them for a long time, and yet kakashi still needs to perform the seals. is it because kishimoto wants it to be more similar to the rasengan which doesnt require seals so naruto and sasuke are a bit more even or what? because to me it seems stupid.
i searched for this using the search function oddly enough but came up with no results, input would be well appreciated
