ok splitting is nothing like clones
shadow clone jutsu MAKES copes of the user and distributes the chakra evenly and allows the clones preform the same jutsu as the original also requires hand signs
spiting jutsu is like cutting some one in half half the chakra and the jutsu power and the toughness basically dont preform the splitting jutsu when the enemy sees it ull most likyl die faster
i saw a prediction a few days ago bout madara used splitting when the fight w/ the first and one half died that day this is a good prediction mabe thats y kishi put this splitting in for the epic battle
