It's not disappointing that Naruto is outclassed, in fact I'm rather surprised so many people are outraged at him and Bee starting to lose. Until the last two mangas I was really skeptical about Tobi and his paths, because I always thought the Pain arc was the greatest and that reusing his 6 path technique was going to tak away the grandeur of my favourite character Nagato.
Now that isn't an issue whatsoever- Tobi and his abilities are a far more badass combination than anything displayed in the entire manga thus far. I was impressed by Naruto's and Bee's usage of version2 tailed-beast cloaks already throughout the manga, but this chapter was on another level of awesomeness... for instance, once Bee caught the edo 6 paths in his octopus hold, I was on the edge of my seat during that 3 second countdown- I was hoping against all odds that Tobi wasn't going to be brought down so quickly. Seeing Tobi slipping out of the ground unharmed while his 6 paths powered up to version2 was probably the most epic moment in the entire manga.
With previous knowledge of tailed beast cloak powers, it was obvious that the battle was decided on Tobi's behalf right there. Edo Madara, complete Nagato, Pain vs Naruto or even Itachi vs Sasuke all seem like childs play at this point. Especially now that it's revealed Tobi's 6 paths are perfect jinchuriki hosts with linked rinnegan vision and enhanced sharingan fighting potential... controlled by Tobi, we're seeing feats of power from the edo 6 paths that Naruto and Bee have never shown- unique tailed beast jutsu's in version2? The 5 tails knocking the 8 tails aside like Pain swatted aside Gamabunta and the toad summons?
To top this off we know Kakashi's mangekyo sharingan is useless against Tobi, and therefore will probably be useless on Tobi's 6 paths, meaning Kakashi and Guy don't have access to any deus ex machina kamui to do away with any tailed beasts.
In summary, the manga has never been better and people that are negative about Naruto appearing weak are failing to see the forest for the trees, as a familiar character once said to Naruto long ago...
