He does do that , but it's not what you're describing it to be
You first agree with me then say I was wrong? Make up your mind. Kishimoto is well known for over-hyping new characters and abilities and rarely, to never fulfill those hypes. Examples being almost all of the Hokage or the Rasengan itself.
I don't see what the problem here is?? Are you saying naruto's speed was over-hyped because Obito can keep up with him?
I'm saying it either doesn't make sense, or Naruto's (and Ay's) speed are far less impressive. The fact that Obito is able to keep up with Naruto with such ease (who previously reacted faster than the Raikage known for his speed) means either one of two things. Naruto's speed was over-hyped and later on brought down for the sake of writing a plot (which is the most likely) or Obito at base level without any power-ups is just faster than Ay and Naruto when they both use a technique to enhance their speed.
Kaguya is better in everything than madara, her being able to dodge/react to something a madara who hasn't even gotten his 2nd eye yet does not mean Sasuke's heavenly hand technique was "over-hyped".
Kaguya isn't more intelligent and focused than Madara. She lost because she got so obsessed with gaining more chakra that she forgot about the plan they had. Her attacks where tricky or smart, they were just massive attacks launched without any finesse. Meaning Madara had far better grasp of combat and how to employ his techniques than Kaguya. Madara with one eye was also able to react and respond to Minato's teleportation, while Kaguya was unable to respond to Naruto's jumping speed. As you can't be faster than teleportation as its technically not a speed measurement, then that is odd. The only logical explanation is that Kishimoto thought it would look "cool" despite it making zero sense within the context of the story as we know it.
This is why
Heavenly Hand Power was over-hyped during its first few uses. Madara was first able to react to teleportation with ease, then he got a rather substantial power-up and now he is not just unable to react to teleportation, but it takes him several seconds to process it. The dude got surprise Alzheimer or something for a second. Yet later on Kaguya is able to react and process teleportation, but is entirely unable to react to someone jumping at her? Hence it is either not her speed that is the question, but the personality behind the reaction. Kaguya and Zetsu were focused on everything else but Naruto, thus didn't see him coming.
Madara was focused on nothing but Sasuke and Naruto, but was unable to react to most of their attacks even when a weaker version of him was able to react to Minato when he wasn't paying attention. This is an example where "cool" triumphs over logical writing.
Bad example here, did you want naruto to fire off the same sized Lava rasenshuriken as he did the first time in the village?? Or the fact that his kids were right there behind him
Just because you mistake something doesn't mean its bad. Naruto used the Lava Rasenshuriken against Kaguya as well. Which was far weaker than he did against Madara. Which at the surface seems to have cost him next to no chakra. This means that either the technique wasn't as strong as first hyped, or Naruto was holding back against Kaguya, making him a massive asshole who didn't take "saving the world" seriously.
