The server should be in USA. WHY ?
The simple fact that they use an "American" server is that in Europe all people handle an internet connection much higher than that of us in the south and north america. And that's a fact we all know .. many people said it should stay in Europe, but for what? servers always done in their own country, because they do not turn around and leave a good "proxy" for Europeans knowing that handle better internet to us.
Another point is to choose a good host dedicate where both places do not handle high ping. as another server that will be released very soon "classicus" which is also very good server, but it handles high ping and high ping servers run out of people ..
A great example is classicus most of its population of players is north and south america, by the great ping it causes, people decide to leave and not to play. and those who remain are few? 60 player? and pay a host of 60 people do not think it is very profitable, while if they do something good where they can implement both continents maintain a ping under their anger very well.
