I and my Free Company are english-only speakers on a Japanese Server. So, naturally, we had our default language set to "E" only, for english. Well, it turns out this was actually hindering our ability to get groups in Duty Finder. Once we started checking each language box, JEDF, our time spent in the Duty Finder dropped significantly. It didn't dawn on us until now that we were actually restricting ourselves from getting into groups where everyone else only had the "J" language selected. Sure, once we changed it to where we selected all languages we got into many more groups - and most of them didn't speak a lick of English, it really didn't matter much for duties we knew how to complete anyways. We've cut-and-pasted a simple phrase from Google Translator to let the rest of the group know we are English-only, a simple greeting, and if they need to give us instructions to please say our name first so we know to copy their message and translate it via Google's Translator
I didn't find the right solution from the Internet.
