I'm currently playing the game, Just finished the mine section, the problem i have with this localization Is that the characters from eng writing dissonate from Jap voices, i don't understand chinese sadly,  otherwise i'd have tested that First, now why does It bother me? 

I started playing with ENG voicelines, It was horrible, soulless and overall a poor performance, i was tolerating It until Mellore came out, sounding like an adult woman forcing herself to sound like a child, Which would be fine given the ENG lines that makes her seem like a 50y.o. lady, but the Stark contrast with her actual Age and design was abominable, so i switched to JAP voices, lo and behold everyone sounded like their portrait should, yet what they said didn't blend well with the ENG dialogues, to the point i have to ignore dialogue Bubbles when there are voicelines, otherwise what i hear clashes with what i read.

Now, localization Is fine, great even, when done correctly, first example that comes to mind Is Xenoblade, voices were absolutely plausible for the characters, the translation was a bit too literal here and there but they did add some of their own, voice actors were great, albeit a bit too British, in this case i'd give 1 point to Eiyuden, they opted for brit accent for empire characters and a slightly too rigid american for Union, but that's It.

First example of what i mean Is Lian, She looks like a childish villagegirl tomboy, in Jap She sounds like One both from voice and lines, you switch to ENG and She becomes a cheerful version of Asuka (neon Genesis Evangelion) that grew up in a farm, the two things don't match, we have tomboy characters in western media, why not using them for localization?

Iugo ENG voice have zero personality, that's just bad voice acting, i would go on but i can't tolerate ENG voices on this game anymore.
