Hasn't anybody ever found it interesting how the Kage Bunshin technique works? How Naruto can so effortlessly have the Kage Bunshin reflect his will or thoughts at very specific times, even upon their very summoning? It's one thing if they're doing very basic things, but things can get downright complex with how he uses kage bunshin, don't you think?
It still to this day blows me away how he can deal with the potential concentration requirements that such a technique, at the level that he uses it, must require.
How does he coordinate so incredibly well without words when we haven't seen any signs whatsoever that the Kage Bunshin can communicate telepathically? In fact, we absolutely know they can't.

I never got how all of this high level planning, executed with such precise timing is possible, and I think I finally may have a reason. Naruto has a natural talent, or knack, for fuuinjutsu. He's using Kage Bunshin to a degree where, on every use, he's literally -- whether he realizes it or not -- sealing in copies of his desired thoughts and strategies into the clones. In essence, he even possesses the ability to provide very specific roles to just certain kage bunshin meanwhile the rest have a different set of instructions, and the only reason they're able to execute on his desires to such amazing perfection, is thanks to his sealing ability. I think it will be revealed that the Kage Bunshin technique is at the very base or heart of mastering very complex and powerful sealing ninjutsu. If there's a technique out there that no other individual uses at the degree that Naruto can, it's the Kage Bunshin technique, even much more so than the Rasengan.
Think about it: What basis exactly did Tsunade have to suggest that Naruto's Ninjutsu style is more like Kushina's than Minato's? Last I checked, we don't know of any techniques that Naruto possesses or uses often that are similar to his mother's. Whereas we do know for a fact that Naruto has Minato's Rasengan and has progressed the technique significantly. I think it's because Kushina was very skilled in sealing ninjutsu, and based on how well known Naruto's impressive use of Kage Bunshin is, I think she can very clearly tell that Naruto has just as much potential in sealing ninjutsu as his mother did.
Only other character we've seen perform Kage Bunshin to a degree anywhere nearly as impressive as Naruto himself, has been Itachi. And Itachi's last act when he was alive, was performing a very impressive Amaterasu sealing technique on Sasuke with just a tap on the forehead.
Think of Kage Bunshin being at the root for Sealing Ninjutsu mastery as similar to how Kakashi felt so strongly that having Naruto, Sakura and Sasuke train to focus chakra to their feet and run up a tree would benefit them greatly in the long run in a number of different areas.
