We've previously announced our intent to merge the Cataclysm and Frenzy battlegroups in order to lower their arena and battleground queue times, and increase the amount of players available for the cross-realm PvP features. Due to the extensive maintenance this merge will require, we're currently anticipating a maximum of 24 hours of downtime for the realms in these battlegroups, which are listed below. We're currently scheduling this downtime to begin on June 19 at 3:00 AM PDT, and conclude at approximately 3:00 AM PDT on June 20.
