I regularly game with different groups and while I have played exclusively on the US servers to this point I have some interest in gaming with friends in Europe on the EU server.
We've seen that you can use a US activated copy of Diablo to access the EU server and it's clear that I will not be able to access my current characters on the EU server but my question is "If I log into the EU server and start creating characters there, will I in any way harm/affect my current US characters?"
IE Does Blizzard require you to commit to a single server?
