For those fellow Aussies who are wondering what the performance is like from the east-coast of Australia, I created an account on the NA server three hours ago and have been very pleased to see that, at least in my part of the world, the ping was exactly the same as that to the SEA server......102 to 105, and so far no increase.
This was with over 11,000 players on the NA server.
Sure...I have to start all over again but hey, it's only a game and the upside is that I can meet up with several US friends who also play WoWs.
Language barrier is also non-existent.
Might be worth a try for those of you going out through Sydney or Brisbane and certainly an option for Kiwis.
