This frequency of English localization issues is unacceptable

That said, I'm pretty sure the localisation team still works very closely with the Japanese team or something (unsure if this has changed over the years. I just recall a thread made by someone on the localisation team some years back explaining how things were being done).

There are dev videos for some expansions such as Heavensward which talk about the localization. There are probably some in the live letters as well.
