Blizzard Community Manager Drysc recently announced on the World of Warcraft Forums that Blizzard will be merging the Cataclysm and Frenzy battlegroups sometime in the next month.

This merging means that the Shattered Halls, Azuremyst, The Underbog, Auchindoun, Coilfang, Blood Furnace, Terokkar, Exodar, Blade's Edge, Velen, Area 52, Zangarmarsh, and The Scryers realms will now all be placed into one single battlegroup.

Drysc notes that the merge is occurring in hopes of lowering queue times. He also says that this is to "increase the number and variety of opponents for those participating in cross-realm battlegrounds and arenas."

Drysc also added that more information regarding the merge would be announced as the implementation of this battlegroup joining nears. Rest assured that we'll keep you updated about it as soon as more info is made available.
