An explanation doesn't make not an asspull. If chakra somehow connects both worlds, why didn't Itachi come to Sasuke and console him and personally ask him to protect Konoha before being resurrected?
Why didn't Orochimaru's parents come to console him?
Why didn't Jiraiya come to console Naruto and Tsunade? Why didn't Dan come to console Tsunade?
Why didn't Kakashi's father come to Kakashi and talk to him instead of just sitting at a spiritual campfire?
Why didn't Sasori's parents come to him?
Why didn't Asuma come back and laugh at Hidan or curse out Hidan?
None of them were Sage of the 6 path for even a few seconds and had Kamui to top.
Hasn't chakra and powers lingered before?
Dead Minato and Kushihna left his chakra to do the "talk" or help fighting Kurama.
Sage Hogomoro is just floating around somehow even after his death ( beasts said he separate them before death and died). Gives chakra and powers to both Naruto and Sasuke. (How much he had initially?)
Indra and Ashura are transmigrating.
Dan went to visit Tsunade and gave rest of his chakra to Tusnade before disappearing again. (chakra transfer from spirit)
Gara was able to be revived by some jutsu and can also use sand now on seemingly greater level(?? but yea) without Shukaku.
Kinkaku and ginkaku using Kurama 's chakra for it got ingrained with the contact they had for short period.
It's not like first time something like this happened. Kamui's connection between the two was also stated before. Now Obito could have given the eye before he died but then Kakashi would might have had them permanently. Of course Kishi let him spend that time talking to Naruto. He couldn't make the death slow enough to lend eyes as well as has his long talk to Naruto. And he many not want to give Kakashi a permanent double sharingan. ( not sure about this part)
Susano requirements got corrected when Madara used it while blind. Unless story ends one can only speculate abilities and writers fix it as they need to.
Now you may not like the development or how he used his options and all that but at least stop spamming the same thread topic you guys. -_-
People getting enraged on behalf of another character who was out-shined (most likely only temporarily- Sasuke will get his panel time I believe) Or fanboying over Kakashis temp power are just...
