How would you fix Kakashi, so he could stand toe-to-toe with the other Kages?
Let's say Kakashi becomes the next Hokage, I don't think he will be able to protect Konoha with his current condition. Especially if you face him off with the other Kages or even the likes of Oro.
He even had problems fighting akatsuki members.
Let's say we replace Tsunade in the edo Madara vs the 5 kage battle, I doubt he would be as effective as Tsunade.
I could be wrong in my explanation above, but how do you fix him so he can hold himself against other strong opponents.
With my other thread, most people if not all, are against him getting senju dna to fix his chakra problem. So what other options left for him to get stronger.
look forward to naurto 607
