There are many players on US realms (Gorgonnash has a sizable Malaysian/Singaporean population). There are several lowyat-made guilds too, on Thaurissan (LoTH) and Smoulderthorn (is Syck still active?).

It all depends on your connection really. Streamyx gives funky results for different IP addresses. For example, 218.111.xxx.xxx gives me good WoW experience (400 to 800 latency is "good" for me), but it is shit for my friend who lives 20 minutes away. He uses 60.xxx.xxx.xxx ip, which is in turn; shit for me =/
