The problem is that they have no clue themself what ninja does a lot of the times and translation in the game are wrong as well so the information inside the game is not "real" at all.

Ice did poor job with that guide and that's all, he copied translations from the game (that are wrong in the first place) since Indra dodge is not "very high chance" like 6p naruto but evasion based then he copied wrong translation from konoha proxy (he didn't have indra himself most likely) about susanno mystery having knockdown and here we are. Game translations wrong, forum moderators misleading people for a ninja that costs what 1800$ ?

In any normal game you could 100% ask and get refund, developer would instantly fix the wrong translation, dropped some apologies and compensation to the playerbase but it's naruto online so good luck basicly.

PS. Yujin is right about Indra not having knockdown from day1 on chinese servers so it's not a bug and won't be fixed.
