Just something that has been in my head for a while that I don't know if it has been talked about before, but who here thinks that Obito's Sharingan stunted Kakashi's growth?
Positives- He gains all the sharingan's abilities as shown by the Uchiha clan which is pretty impressive.
Negatives- His chakra drains much quicker than an Uchiha when using it because his body isn't made for it. I'm sure there are more but I can't think of anymore right now.
Kakashi was a Jounin at the age of 12, something we haven't seen confirmed from too many other characters (Itachi's the only one that comes to mind). So while he does get better from his 12 year old self to his manga starting self, I don't think it was as big of a jump it could've been.
Pretty much all of the Uber-nins in Naruto have high chakra levels.
And if they don't have high chakra levels then they have other non-chakra intensive skills. Out of all the S-Rank nins only Itachi has a Chakra level under 3 in his databook entry. But since most of his skills are with Genjutsu (not that he isn't bad-ass with his other skills). He doesn't need to have a high stamina rating since Genjutsu focuses more on control than amount, at least that's how I interpret it.
But everyother ninjutsu centered ninja has a rating above 3.5 that I've seen in the databook.
And I think it's the sharingan's fault. It's not like he doesn't have bad blood, Sakumo was respected on the same level as the Sannin when he died. So it's either outside circumstances that affect how Kakashi has developed (his whole somewhat graduating team is dead) or there was something that held him back.
I'm sure there is better ways to argue this, but I want to see what everyone thinks on this.
