Servers for each Region

[Ramsey]

I somehow doubt that if the whole thing with Ifrit's attacks still hitting people despite being out of range client side still continues to happen.

This has nothing to do with server location, and everything to do with the protocols the game is using. There are various ways of handling what data is handled client side, what data is handled server side, what data is sent, how many checks that data goes through, and how those checks are applied.

It's a case of poor decision making, not a case of "the server is too far away."
