First off It's not a battle of people its a technique match up. Even so Two battles vs sharingan users with out eve contact and the old hag of the sand knew how to fight sharingqn users while not making eye contact. It's easier not to look into someone's eyes than it is to stay completely out of their field of vision. Again attack range goes to kamui. Sorry dude its logic. Don't spooge oppinion as fact.But how many people can fight without eye to eye contact? I doubt many could, and especially against someone as dangerous as Itachi. Kamui is also dodgable, whilst Tsukyomi isn't.
