What were people confused about that the viz translation cleared up? The only thing the scanlators did bad was having me think sasuke was the one thinking when it was talking about how he can use rinnegan and the chidori and whatever, but in actuality it wad Kurama that was thinking that. Everything else was clear I though. What some people thought he didn't say that he lost? How the hell is that possible.
And viz should have translated the last part as scaredy cat, not buffoon, that is what Sasuke said to naruto in part 1 all the time isn't it? They obviously wouldn't leave it in the original Japanese though don't know why people would think that, viz does not leave Japanese terms, that's the point of them translating.
