This has to do with Obito vs Kakashi, Guy, Naruto, and Bee. We clearly saw that when Kakashi went after the Gedo Mazo and used Kamui, Obito was actually able to stop it because of his own MS. However, we later on saw that the only counter the 4 could make up for Obito's Kamui was to use Kakashi's MS in order to send attacks to the Kamui Dimension to hit Obito wheneer he went intangible. My question is why didn't Obito just disintegrate the Kamui portal like he did when Kakashi used Kamui on the Gedo Mazo? Is it possible he can't do it while he's intangible? If that's the case, then howcome he wasn't able to undo it when Kakashi used Kamui on the Shadow Clone of Naruto? He wasn't intangible there. And yes, Obito didn't know Kakashi used Kamui on it, but that just makes it even more stupid since the dude literally had a Sharingan, Rinnegan, and was the original user of Kamui. So, what gives? Did they just have to nerf Obito for plot?
