Be aware that the server list and distribution you're seeing for this weekend's test are not the final numbers for launch. We'll have more servers in all datacenters - so more EU servers, more East and West Coast US servers. This will include all server types.
Why aren't you seeing those for this weekend (so far)? Because a major goal for this weekend is to stress test our hardware. When we reach those goals (and we're already close) we'll look into opening up more servers as required, globally.
As a specific note to EU English players; remember you're able to log on to any server you wish, including North American. Generally speaking gameplay performance on NA servers from Europe is still reasonable.
