Besaid is not JP. It's the unofficial NA RP server. =P
Seriously, I picked Besaid because of it's large English-speaking population (I'm sorry, at the end of the day, I just want to be able to talk to someone in my native language and not get frustrated because the auto-translator doesn't say what I need it to say).
I see very few JP shouts on Besaid in comparison to the large number of English shouts.
And
Tibian's post is pretty long, so I won't quote it, but I agree 100%. I'm all in favor of designating language-based servers for pretty much all the reasons he mentioned.
This would be great. Give those who want to be on a server who speak a primary language the option, and those who like cultural diversity on another.
