Ok. I'm going to do this real slow. So now you're telling me Kakashi will cover his body with what? One kunai in both hands blocking his entire body. Even dodging there is no way. Come on this isn't the Matrix. He will at least get hit at some point.All of Sasori's 1000 needles were not coming straight at Sakura with pinpoint precision.They covered a wide area to make dodging very difficult.Just as you said the sharingan deals more with precision so kakashi will just block/dodge the needles that are coming straight at him "man".
Also I was not aware that the sharingan only has precision capabilities.
Maybe i am mistaken but it has a variety of qualities such as Genjutsu, Reading movement, seeing through genjutsu, copying jutsu, amaterasu, tsukyomi, susanoo, Kamui, and time space jutsu.
But maybe i'm mistaken.
And I know the capabilites of sharingan. To my knowledge sasori didn't use Genjutsu. Kakashi can only use Kamui out of all those listed to my knowledge so unless you're telling me he can use the tsukyomi,susano'o and time space justu like Madara then please show me the manga pages. I will surely back off on the arguement.
