Its because the selection of language does not affect what you see in the way of forum posts. (Which it should just have separate forums for anyways). If they feel the need to combine I do feel we may agree. The language selection should affect what posts we see (IE see only EN posts, FR and DE should be filtered out). Currently this is not the case.

Probably because Europeans speak a lot of languages and England will probably use the Euro server - it makes sense for both english and non-english speaking europeans have access to the same information. It makes it look messy, but that's what you get for having these types of servers.
