for those who haven't been on lunia, it now has regional servers that you can switch between - West US, East US, Brazil, Europe, Singapore and Japan.
It's so ridiculously smooth for me in the East US server that it's hard getting used to. Nobody pvps there anyway.
It seems for east US and the Asian servers, playing in the West US server is tolerable enough so there's been some fun pvps going on in the West US server
