sigh you are horribly misinformed... ITACHI'S TSUKYOMI lasts 1 second in real life and days in outside world... ITACHI had a natural aptitude to using genjutsu and tsukyomi, While SASUKE had a natural taking to manipulation of amaterasu flames...
AS DANZO said, sasuke cannot control the opponents perception of time like itachi could..... thus sasuke cannot make it 1sec-3days... if you read the manga you would know that....
Tsukyomi is not a genjutsu that lasts 1 second.... Tsukyomi is a genjutsu that can change depending on its user
Your ignorance in manga related facts, that were clearly stated by characters is beginning to tick me off ....
Yeah I thought since Sasuke was given Itachi's jutsu that he should be able to use it the same way as Itachi. Also i didn't think about him having his own MS jutsu too, I know enton is shape manipulation of the Amaterasu but it still should be classified as a jutsu separate from Amaterasu like Sasuke variations of chidori and Naruto's variation of rasengans, they're all shape manipulation (rasengan is also chakra control). So do you think Tsukuyomi changed from Sasuke MS? Sasuke seems to paralyze his enemies with it then attack so I wonder what's the full aspect of his Tsukuyomi since Itachi had both space and time control so Sasuke might have one more ability for his Tsukuyomi. Any ideas?
