Jiraiya is stronger than Tsunade and war Kakashi aint on the same level as Obito, he was equal to Obito in the kamui world
nothing suggests kamui world increases stats
1.- Stamina was an issue for Kakashi mostly due his sharingan which wasted more chakra since he is not an Uchiha, without it, he can spend that chakra for other attacks and last longer. So Kakashi lost something but also gained something else.
Chidori does not increase his speed lol, neither does purple lighting. The problem with Chidori was the light it produced which blinded Kakashi reason he can counter sneak attacks. With the purple lighting, this doesnt happen so Kakashi doesnt have the same blind spots which he had with the chidori.
Minato verbatim says it makes you move to fast making you uncertain of opponent's attacks but ig the manga is wrong and your right. Am i correct??
Obito said he made Kakashi pierce his heart, so Obito was still superior.
Kakashi still had the strength to pierce him, Keep coping bud
Boruto kakashi is weaker then kakashi from the war arc
Shin uchiha said that times of peace has weakened shinobi.
