Did I hear u say naruto was trained better than sasule in shipuuden,when sasuke dealt with yamato,sai and naruto at the SAME time,if not for orochimaru,they would have been dead.minato did kakshi a favour,why shouldn't kakshi return it,and I never said kakashi SHOULD take sides,just sayin that he never taught them equally,if not for jiraiya,I wonder where naruto would be now
I didn't say Naruto was trained better - also Naruto's main training in Shippuden happened after the confrontation with Sasuke if I remember correctly - I said that Kakashi spent time training them seperately both in the first serie and in Shippuden.
In the first serie, Sasuke got a bit more attention near the end of the first part and in Shippuden it was Naruto. Also the fact that Sasuke managed to win from Naruto, Yamato and Sai at that time in Orochimaru's hideout, isn't necessarily Kakashi's fault.
Naruto spent three years training with Jiraiya, so you have to blame him then for not training Naruto enough, while Orochimaru did train a lot with Sasuke. They each spent three years training with a Sannin - blame Jiraiya then for not training Naruto enough.
Also, it's not like Kakashi asked Minato to consider him almost like a son - Minato chose to act like that on his own volition. Kakashi is some sort of father figure to Naruto and Naruto doesn't seem to mind the type of relation they have.
And again go read the first part of the serie: Kakashi taught them all equally until that one point in the middle of the Chuunin exams. And even then Naruto got trained by Jiraiya so it wasn't like he was left out in the cold. Both got trained.
I think Naruto got more training with Kakashi in Shippuden than Sasuke in the first serie.
And again, Naruto improved during the time with Team Seven. If Kakashi truly didn't train him well enough, he wouldn't have been able to improve.
The case would have been different if you talked about Sakura. Out of the three of them, she never had any special training session with Kakashi as far as I can remember.
Both Naruto and Sasuke had special training sessions with Kakashi, except Sakura. But I don't hear you complaining about unfair treatment for her, even though she was never shown to have received any special training of Kakashi
