1) Are you going to put double-quotes around field contents? There's no real standard for this, but the nearest thing to a standard does seem to be to double-quote field contents, see http://en.wikipedia.org/wiki/Comma-separated_values for example. I know it's not strictly necessary, but I don't feel 100% certain that Blizzard won't one day create a server with a comma in its name

2) Are you going to prefix non-EU servers with their region? I presume all the non-EU ones in your list are US at the moment??? Does that mean that there are non-EU, non-US servers that aren't in your list at all, e.g. Asian ones?
3) The per-server files contain the server name as the first field. This is redundant, as it can be derived from the filename.
