Answeres to Itachi vs. Gai nonsense:
#1 Taijitsu is strong against a sharingan user
The sharingan's weakness to taijitsu is being vastly overblown. Let's look at what the sharingan can do:
1) see through taijitsu, ninjitsu, and genjitsu
2) copy taijitsu, ninjitsu, and genjitsu
3) play mind games with the opponent
The sharingan still gives an advantage to it's user on all three points. It helps see the enemy's movements
better, can still copy taijitsu techniques (even if it requires the user to already have the speed to perform
them), and (since the user has likely used it to copy ninjitsu before) provides the user with a wide range of
ninjitsu and genjitsu to use. Furthermore, it requires the taijitsu user to not look into the sharingan user's
eyes, which would make it more difficult for them to fight.
#2 Gai is faster than Kakashi
Even if this is true (can anyone actually back this up?), it's only put Gai ahead by 1 match out of 99, so
how much of an advantage is this going to give him against Itachi? If anything, it says that Gai has to be faster
than a sharingan user just to fight evenly. And Itach is faster than Kakashi as well. Much faster.
#3 Itachi left when Gai showed up
Itachi works for a secretive organization persuing some secret goal. Fighting a huge battle with half of the
ninja in the village isn't the best way to keep a low profile. Remember, Gai said that ANBU were comming
as well.
