Just want to point out, that there is no evidence to Sasuke gaining a speed boost, from EMS and after(Meaning Rinnegan). Also, the bisecting Madara thing, can't be used as a feat since it was a sneak attack and Madara was occupied with eye surgery at the time.

Anyways, none of that has anything to do with Itachi. Having already showed that the YM is not as powerful as some think it is, lets move on to Itachi's genjutsu. Most of his genjutsu is Sharingan based, meaning eye contact is needed, however there are ways around this, as according to Chiyo, multiple allies can overcome Sharingan genjutsu. Tsukuyomi, though powerful is no exception to this rule.

As for Itachi's finger genjutsu, it's not powerful enough to put Kabuto under genjutsu so therefore, not a problem for higher level shinobi and certainly not a one-shot technique.
