but kakashi didnt always have the sharingan, and is said to be a genius. shikamara is a super genius and has no bloodline limit. the only person that i see people say is a genius because of a bloodline limit is sasuke. if he is so much of a genius then why hasnt he mastered his sharingan. his brother mastered it when he was 8 and sasuke is what now about 13 and still hasnt mastered it. some genius. neji is said to be a genius but he proves why since he is from the branch family and knows serect techniques on his own that are only pasted down to the heir of the clan. he mastered his abilities, itachi mastered his so saying they are genius i can see but sasuke. where is he one at.
