WOW Community - translations

I can choose the language of wow community, but nothing happens except the “site language” will change. There is an option to translate posts in this language.

Why don’t we directly translate all posts in the language a user has selected for WOW community’s but allow the user to see “original post” if wanted.

Instead what happens currently if I select EN as my language I see ALL languages and a mixed feed that has no value to me (if I can only speak EN).

Here are two examples of the EN page.
