I agree with everything he said though
That shyt was complete damage control because simply put, if Kakashi doesn't get some sort of power up, everybody's fukked, Sakuras fukked namely, they got no healing ninja so Naruto and Sasuke are fukked
Kishi wrote the death and the move that killed Obito in such a way that there was no way Kakashi could get the sharingan(something I predicted would happen) so he had to bullshyt
I been watching/reading this anime since 2006 and this was by far the one time where shyt completely hit a brick wall in writing. For one Kakashi couldn't use fukkin Kamui more than 4 or 5 times, he didn't have the chakra and his eyes were starting to go out. Now the nikka (after almost being completely drakned) pulled a massive ass Tailed Beast sized Susano'o?
