The fact that there’s still people convinced Kakashi became weaker when he lost his sharingan blow my mind.
Man legit lost a huge disability when Madara took his sharingan. That thing was eating his chakra 24/7 and he had to keep track of how often he used it and plan his attacks to the letter because if he used it and it didn’t work out he was f***ing himself over. He was putting himself into a position to die if he didn’t use Obito’s eye properly.
He created two new jutsu’s in the span of six months before becoming Hokge, after the loss of his sharingan
He kept the use of all the elements and his various jutsu’s he learned with that sharingan, faced off a three day attack with his quartz wall Jutsu, created purple lightning which is stronger than Chidori, and still continued to improve himself.
Plus like… dude was a prodigy and an 11 yr old jonin BEFORE getting the sharingan. He never needed the sharingan to get strong and at the end of the day all it really did was give him a cool new power that also disadvantaged him all the time even when NOT using the sharingan.
The sharingan was a curse for Kakashi that he bore at Obito’s wish, and while it is the reason he got his name ‘copy ninja’ (since he could not have copied 1000 jutsu’s without the sharingan) it’s not what made him a terrifying foe in battle
