Kakashi conceals Sharingan so he won't waste chakraSasori, Obito, Orochimaru, Jiraya, Tsunade, Minato, Itachi, Danzo, .. So many can counter a genjutsu that requires "eye contact " to begin with.. Try thinking what would happen on the battlefield .. Buffoon
Sharingan can't see through fog yet somehow it can see when concealed?
Danzo used it while concealed and NO eye contact so it requires NO eye contact? How could he make eye contect if he couldn't see out of that eye? EXPLAIN PLZ
ALL of the peeps even Itachi can't break KA best they can do is get hit or in Sasori's case he is a puppet and Danzo would have to use KA first
