Do you even read what I write??Did I ever said that Kakashi has low chakra reserves??I just say the exact opposite.
My main argument is that Kakashi's body doesn't have any of the traits the senju have.And if you can,prove me wrong.
And I know perfectly well how many jutsus Kakashi used in each and every fight of his,I don't need lectures by you on what Kakashi is and isn't capable of.
And how exactly do you seal DNA??Has anybody else in Narutoverse demonstrated such jutsu??I don't think so.
And if his father cared enough to seal him to protect him (even though I don't see how sealing power can protect somebody) he might as well stick around and not kill himself to do so.
