FRS is big noisy technique, naruto will never surprise sharingan with that.Naruto has device tactics before the Pain arc, Naruto can use clones which gave him info on how to approach Kakuzu in order to land his Rasenshurikan.
A sharingan that can suppress biju is not nothing. With CM 3T was enough to brake tsukuyomiI'm talking about 3 tomoe sharingan and yes its futile against Sm Naruto in almost every aspect.Ma and Pa can snap him out of genjtusu and his Sm mode extend his punching reach something the 3 tomoe could never track.
Sasuke's sharingan is nothing his genjutsu won't even work on Naruto.
Ma and Pa? Pain arc naruto is yet to show he can even summon them. Nahashi has bigger range then kumite.
Again, he has never shown to able to summon ma n pa. Jiraya took whole lot to do that. Genjutsu isnt from get go. It takes time as seen with pain, countered by self inflicted pain lol.He's still able to use tactics during the Pein arc, the how intelligence thing is the only thing you can agree against since Naruto completely nullifies Sasuke's attacks.He created clones without a Rinngegan user knowing, he can easily accomplish this against a puny 3 tomoe Uchiha cub.You must be registered for see links.He can create summonings such as Ma and Pa who can start up the sound genjutsu from the get go.
Sharingan has enhanced perception it doesnt fail to spot minor details like rinnegan does. Clone spam isnt tactics, its the only shit he could do actually. Sasuke has summons too u know.
A sharingan can see chakra levels. To fool it naruto would have to create even amount of chakra in clones and himself, that would be huge waste of SM power, it would deny him ability to make any FRS. Sasuke has AOE attacks to deal with them.He's done that against Kakuzu and Sasuke won't be able to keep track of the real one unless you have real evidence of him doing so.
