I used privates servers and i found a launcher who permit you to CHOOSE if you want to play in China, europe, us or private server^^
This program auto change the realm name and connect you to the sever you choose.
when a new update is comming, just clik on eu server and it start to update.
when update is finish, click on chinese server and play.
if servers are down or need fun, go private...
no need manual change with wordpad, it is automatic. just need to click.
send me MP if you are intrested
