lmaooo ^ Firstly being an uchiha doesn't mean you're a genjutsu expert.... dont talk bs... uchiha were not a genjutsu clan specifically.... there eyes could simply cast genjutsu via eye contact, that doesn't mean they all could use it, since according to jiraya its very rare and requires very high intelligence...
Orochimaru's genius came from experimentation? don't kid me.... orochimaru was called a genius just like sasuke.. since he was in the academy.. before he even started doing experiments.... so that's bs...
"A GENIUS THAT COMES ONCE EVERY 10 YEARS"
right? what merit does that statement hold? Oro was a genius of his 10 year group, minato of his, itachi of his etc....
And once again, Orochimaru spent his LIFE researching sharingan, the uchiha clan, etc... and still looked into a sharingan
You come telling me what? some silly theory based on conjecutre that minato will somehow magically know not to look into sharingan when geniuses (kakashi,orochimaru) and normal jounins(asuma kurena, gaara(kazekage), (raikage A) etc who all were around in the times of the uchiha clan all looked into itachi / sasuke's eyes.... and the people who didn't aka oonoki, chiyo and gai , all fought genjutsu using uchihas before...
you seem to think that just because the uchiha has genjutsu the ninja would inconvenience themselves and look at their feet... no MOST ninjas can't fight like that unless they trained... which is why oro, asuma etc all looked into itachi's eyes even though they KNEW and oro especially who was his akatsuki partner , knew that he was a genjutsu master
And the only people who didn't (chiyo , gai , oonoki)
