Can you actually prove that Hunter is somehow inferior at CQC? Because they aren't and the idea is laughable. And yes, you're right, monsters are not people, it is just that... isn't really relevant. Hunter is about the same skill level as Naruto. Can we move on?
If Naruto gets hit, his powers are nulled. From that point on he may as well be fodder compared to Hunter. He is also going to take more damage than others due to being at least relatively intelligent (a genius by no means to be sure, but still, he should be along the lines of intelligence as Elder Dragons).
Naruto has no way to conclusively win except by (maybe?) Shadow Clones, but those get nulled quick against Dragon Element.
Additionally, Dragon Element is not a feat. It is a power. An effect of weapons.
Because you seem dead set against using that gosh darn search bar, here is the first result. Elderseal prevents enemies from using their "aura abilities".
Basically, the arguments for Naruto boil down to "Well Hunter has only fought monsters before and not people so lul" (weak argument to avoid the fact that these monsters are in fact incredibly skilled at combat), "well naruto has ninja magic so lul" (which is additionally weak considering elderseal nullifies pretty much any ability not natural to the character) and "lul he is naruto lul"
Hunter has the versatility and hax to take down Naruto, between making Naruto unable to detect him, increasing probability in Hunter's favor, attacking Naruto's soul, and power nulling essentially all abilities on contact.
