About the genjutsu, I'd think twice before I disagree with Kishimoto. Since Kishi's 3rd Databook names all his illusions including Tsukuyomi short range then at long range his means of casting genjutsu won't work since you're out of the tech's range.
So apparently it magically stops working even though you can see his eyes or finger?
What does short range even mean? Did it give it a numerical value? 50 yards? 100?
There is alot of ambiguity in the Naruto manga, I just use logic. Clearly your hatred of Itachi is keeping you from doing this, because Itachi explained his genjutsu.
Itachi said that he can do genjutsu even if you only look at his little finger. So if you can see his little finger but take a step back what does that do? How about two steps back? 5? 50?
If you can see his finger, or his eyes, or basically any body part he wants, he can get you in a genjutsu. So the manga says you have to look at him, while the databook says short range. Hmm, what am I going to trust? Common sense and the manga? Or a very poorly defined limitation to the distance of his technique?
