Okay the shortest version of this thought is:
It isn't uncommon in the ER Lore community for people to reference the "original" JP text for item descriptions or character dialogue to support, disprove, or add nuance to their points and opinions, and not infrequently, the English text and translation is cited as being incorrect, incomplete, or misleading in comparison.
An example of this I saw today was someone who made some genuinely interesting and insightful observations regarding the Divine Gate in Enir-Elim having several different object layers to it - the most recent being Hornsent corpses that bleed, the second a more solidified mass they posited to be Shaman, and the oldest being a tree texture with ropes around it not unlike Korean and Japanese customs. The whole post is very interesting and I recommend checking it out but the bit in particular I am referencing comes near the middle, where the author talks about Hornsent's lines regarding Miquella and the salvation of his people.
As per the original post, in the JP text Hornsent refers to the Erdtree as it's own entity, something deserving of its own ire and resentment, is an impure or corrupted object that needs to be purified, and that Miquella is specifically offering the Hornsent people "salvation" and not "delivery". OP talks about some Shinto concepts as well, briefly compares them to Christianity and wraps up the section by concluding the Hornsent must sacrifice something to and/or alongside Miquella to be granted this.
I take no issue with this reading at all (I personally disagree with some of the readings and conclusions but that's not the point of this post). How this relates to my thoughts on the fandom lacking insight or context on the role of translation and localization does come into play here though, finally.
In the English version, Miquella is very much a Christ-like savior figure, sacrificing parts of himself to atone for the sins of his mother, Messmer, the Erdtree, and all the people who worship it. He himself is the sacrificial lamb who has come to deliver the Hornsent from their suffering, and give them release from the curse of hatred and resentment.
This isn't a *huge* difference on the surface from the JP version, but it has very different cultural implications and resonates much differently with people raised in a culture saturated and informed by Christianity in the West (or USAmerica, at the very least). It's much easier for a western audience to understand the religious, spiritual, and cultural weight of Miquella's actions when its framed in a religious lens that's familiar. That is really my point: it's not "incorrect", "misleading", or "bad" translation, it's what translation and localization is. Making the content, motivations, and story resonate and click to people who might not be familiar with or even understand a concept in the original language or culture.
That's the long and short of it, really. If you were to leave the JP text with all of its references that rely on the audience being familiar with Japanese creation myths in the English translation, most English-speaking players would miss the significance, implications, or meaning. By shifting it to match their cultural expectations, there is a higher likelihood they will understand the original intent and gravity - for them to understand the story as you intended in a way that makes sense for the context they have.
Obligatory: This isn't advocating for erasing, removing, or changing cultural context. Personally, I think it's more interesting and insightful to go out of the way to learn or explore story intent and meanings the way they were originally conceived. Elden Ring is such and interesting and complex blend of Western and Eastern mythology and ideals, it's hard to neatly separate them out or follow the through lines of entirely original intent, considering there are two (realistically more) authors.
Thanks for reading, not sure if I got this thought out 100% right but *shrugs*
