Kakashi is not the same tier as Sasuke guys.

[pateuvasiliu]

Now, Kakashi may have the eye but he lacks the body of a Uchiha, he doesn't have the stamina to keep his Sharringan for too long, hell...

lol part 1 feats.

Kakashi's been fighting with his sharingan for a long while. For days during the war and for a full day vs Naruto and Sakura.

His stamina is perfectly fine nowadays.

If he gets 1, he'll be top 15

He already is top 10.
