reason why kamui he is deadly accurate with it if he can aim it he could take off a vital limb he could kill anyone
the problem is this
line of sight
chakara required
stress on eyebut the one immune to this is
sasuke: sasunoo will get hit first
naruto: speed
tobi: phase no jutsu
edo's: regenerate
my argument that most other ninja even kage got nothin on him
If you're going to say Naruto because of speed then what about Yotsuki A and Minato? KM naruto is only a tad bit faster then A, he was just barely able to dodge him and Minato is not only a space time master of the highest calibre behind Tobi offcourse, but his transportation with Hirashin is instant and his reflexes and reaction time are unrivaled. Kakshi would never be able to hit those two.
There are also many others who can avoid Kamui, Zetsu has one hundred thousand real clones, let's see Kakashi try and Kamui all of those. Konan can turn into paper, kamui isn't gonna work on her, against Tobi, she had blown up more then half of her body and still recreated it with paper manipulation.
He also can't kamui all the six paths of pein or even real nagato, every jutsu requires chakra to be maintained and nagato has the preta path to take care of kamui, without the chakra in it there will be no kamui, preta absorbs all ninjutsu. In any case nagato's reaction time was enough to keep up with KM naruto even though he was crippled, so he can react to kamui.
Let us also see Kakashi kamui the third raikage's limbs, he probably, no, he definately fast enough to avoid kamui and besides he is the strongest shield, we can't be sure that kamui can take away his limbs, he might be able to withstand the barrier, besides, Kakashi would die long before he activated kamui, the raikage are too fast and kakashi doesn't have sasuno'oo or blaze release to protect him. Definately aint fast enought to keep up, even sasuke is faster then him.
Mayn there are many other people that can pawn kamui as well, stop trying to overate kakashi.
