and thats your problem. i can provide proof that it is his disease. if the manga stated it their would be nothing to prove. your asking for proof of something you not going to believe. you asked for proof and i can give you 100 reasons why it is this disease but the one "proof" you have is that the manga didnt say it was that. you dont have a answer for why it isnt that disease or why sasuke did close his eye so you will just say the manga never said so .. . .even though you asked for proof. kind of a hypocrite really.
WHAT.THE.**** ? So, if Manga never states that Kaguya has a weakness, will you just go into the conclusion that she "must" have a weakness because she seems invincible, even when the manga has never stated so ? Kishi writes the manga, not you, so until the manga explicitly states such, you're just speculating and making theories without the support from the manga. I didn't make a theory on why he closed his eyes, I said that the manga hasn't stated why he closed his eyes, so the only one speculating here is you.
Well didn't Naruto said it was like a teleportation jutsu? Never said it actually was did he? I do think it is but you said manga proved it was which the scan didn't really. Anyways, you can't assume Sasuke doesn't need a break with his eye just like they can't assume he does, we can only go with what the manga shows or tells us. I see people saying Sasuke's jutsu is faster than FTG when it was never even compared to it and all the fastest speed were such as A, KM/BM Naruto, Obito, Tobirama.
I do think Sasuke might have to rest his eye since he did have to close his eye, we seen this before in other Sharingans jutsus like Itachi's Tsukuyomi and Amaterasu, Sasuke's Amaterasu, Kakashi's Kamui. It might not be the jutsu but more of the eye in general; if he over use jutsus with it then he might have to rest it. Obito's Kamui only last 5 mins so Sasuke could have a limit or might not but he did have to close his eye to rest it after using his s/t 3x. I think it's only if he uses it without enough time between each is what make him have to close it since he used it more against Madara and not as much with Kaguya.
Naruto (Masashi Kishimoto indirectly) stated it and Sasuke (Masashi Kishimoto indirectly) didn't deny nor correct him). manga has never stated nor shown that he needs a break with his eye, so until then, it is fanfiction, they're giving him weaknesses that manga has never shown, I'm not giving him anything the manga hasn't shown. Both Sasuke's S/T are on par in speed, they're both teleportation, therefore, they're both instant.
Again, Manga has never stated the reason he closed his eye, saying that he needs a break because of that is speculation to the max. Comparing different Dojutsu is not helping your case here. That it all speculation, the reason why he closed his eyes was never explained nor stated, so we can't jump to conclusions here.
