The next World Restructuring Beta is coming soon, and we’ve put together some high-level information so you know what to expect. We will be running the beta from Friday, January 12th to Friday, February 2, beginning and ending at your region’s normal WvW reset time.
As with previous World Restructuring betas, if you would like to be on the same team as your guild, you will need to set that guild as your “WvW Guild” via the Guild Panel. You’ll need to do this by 11:59 PST on Thursday, January 11th for the start of the beta. There will a second team creation event for the last week of the beta, and you will need to have your preferred guild set by 11:59 PST, Thursday, January 25th.
