I live in the middle Europe and have 110 ms, so no problems at all for me (I am not using battleping or anything else), but I believe it would be fair to add European servers. It wont change my gameplay much but it would definitely help some people.

I think that in some interview Yoshida said they tried playing the game outside of USA and that they know there is a problem with latency and that they would like to fix it... some news on this would be appreciated.
