For weekday events though, the thing is western Europe and eastern NA are only 6 hours apart, meaning you can (barely) get both zones in. The difference between Europe and Asia or Asia and NA is 8 hours, so a weekday event for Asia and Australia would pretty much have to be exclusively for them.
They should do this sometimes, yes, being an International server. But the majority of events will ofcourse be at the time that gets the most people in. And certainly the first few events after such a long absence should be. But hopefully you people in different timezones will get an event too soon.

There is also the issue of most event volunteers probably being in Europe or NA as well, making it difficult for them to run an event at a suitable time for Asia. Spiderweb can make a specific effort to get some event guides in from the Asia timezone ofcourse, but it still depends on if they get enough volunteers there.
