more about the sharingan another cool thing wold be that after would be the speed that it grants the user. So we have its genjutsu[teleport thing either automatikly or by left clicking] its ability to copy[stunning the enemy when he his you] And lastly its reflex and speed that it grants the user. So if you use chakra haste and then saringan you will be able to run a bit faster. So lets say you are with friends trying to o somewhere you can move faster and reach there faster and if telepot too you have a preety good way of saving your self from enemy strikes. And i think uchihas need this because they have only 2 attacks and the third ability is made for blocking so at least we need that blocking to be worthy.
