Well....if this is the Viz...then I'm convinced. No one as of currently has a "counter" to Kamui except Minato and Kakashi. Though....I still believe Madara can evade it, and defeat Obito. He just cannot "stop" Kamui. If the Viz is the most official translation? Some say ***********...I'm leaning more towards the Viz.
I'm not going to pretend I'm anymore knowledgeable than you are. I can only use critical thinking and reasoning. Why do they claim *********** and others are a better translation? The only viable way would be that someone/a group of people is translating from the raw themselves and comparing translations. How accurate is that
someone's translation? From experience, there's many times where there's no literal translation, so the interpretation depends on the translator? I'm ignorant of the Japanese language, so some claiming other translations to be more accurate could very well be right. My problem is why should I trust them over the Viz translators? They're recognized as the official translators, and is paid for it.
I don't mean to upset the apple cart, but any opposition against Viz would only be one side of the story. They could just as easily claim that no one knows what the hell they're talking about. I listen to those saying which translations are better, but I don't go "Thanks for telling me that! Wow I never knew." I simply listen. I may do my own research someday, just be bothered at the moment.
Mind you. This is the voice of an ignorant person, so take it with a grain of salt.
