@juju14:
You want Kishi to do arcs of Sasuke training??? This is a waste of time. Naruto always gets the training arcs becuase of main character, but you just get tell or see him training for a second. The only time we ever saw him train was with Kakashi and that was like one chapter. The rest of the times characters just tell u he likes to train like Kabuto etc…..
Both options are fairly bad; Sasuke pulls half-a-dozen powers literally out of nowhere (ex. the hawk summon, using Susano with better control than Itachi ever did) with no foreshadowing whatsoever, meaning that he can be as strong as his current opponent if not stronger at all times due to the fact that he can pull any power out of nowhere and the hardcore fans will accept it. Meanwhile, Naruto takes about ten chapters training to learn a single move, only for that move to be useless against the next opponent, requiring him to go through another training arc to learn another new move while the rest of the ninjas who are present in the area fight and fail to defeat this opponent before Naruto shows up, having mastered his new move after a few (real-time) months of training. This pattern repeats itself for a good portion of the arcs that Naruto was involved with (summoning - Gaara; Rasengan - Kabuto; Rasenshuriken - Kakuzu;Sage Mode - Pain).
Between the two, I'm not sure which I dislike more. Naruto's constant training is starting to get on my nerves (didn't he spend two and a half years training between the time-skip? What did he learn, then?), but at least it's better than Sasuke getting into fatal situations, only for him to gain some new superpower that he conveniently never used or had before this point, having gained it magically with no effort whatsoever, which allows him to win or at least escape with his life.
