The game is totally unplayable here too :/
Don't know if it has something to do with the fact that here in Finland the client might have to connect with players overseas.
I'm just afraid that they might not be able to get P2P working for everyone, and some of us will have to play single player because of that.
As I said in an earlier post, I'm playing from Brazil, and I had very few problems in a good few hours of 'playing'. Mind you, I did not try to interact directly with any other human player (using TeamSpeak, or the like), so maybe 'lag' would have been more noticeable if I did.
That's not a great sample size, admittedly (one person), but it does seem to point to something other than 'being overseas' (or distant from servers).
