It's not like Kakashi can so easily copy this form of training, it would still take him years of nigh-constant training (as naruto trained about 50% of the time for about a week -years of nonstop training-). Also his comments about reserves (ranging from twice to four times Naruto's chakra) suggest that every Rasenshuriken has about half Kakashi's reserves worth of chakra. It took Naruto years-equivalent to properly use his chakra nature, not necessarily apply his chakra nature to the Rasengan. Once Naruto figured out a shortcut of adding his chakra nature to the Rasengan, it took him about, let's say, a week to almost perfecting it before he and Yamato had to help Kakashi and the others. But your right about the chakra reserves issue, though Thekillman wrote: So yea, my point is that had Minato lived, he almost certainly would've succeeded. He simply didn't have the time to finish it. I think Kishimoto thought near-instant Rasengan delivery was OP enough. Minato in Sage Mode, using Hiraishin to deliver point-blank Rasenshuriken would probably make him the strongest Hokage and it's pretty much the strongest jutsu combination i can think of without kekkei Genkai. Well maybe with the Raikage's jutsu it would be more broken, but that aside. Hirashin + chakra-natured Rasengan is OP enough, lol
