Well one reason I play on a US server as a European is the constant war of languages in chat. I'm no native English speaker myself but I prefer a server where everyone speaks English and not a dozend different languages even if it is labeled as English server.
Well as for the names, happens all the time. I'm a bit worried about my Miqo'te (seeker of the sun), I saw the post about their names too late. While it's no silly name, it doesn't follow the specific rules for Seeker of the Suns. Hope they will offer a renaming service.
