After successful testing on the PTR, we are pleased to announce that the first Cross-Language Battlegroups have been created today. This new feature combines Battlegroups from different languages into one, expanding the pool of players keen for PvP action in both Arenas and Battlegrounds.
Players from realms of different languages will only ever face each other as opponents in battle and will not be playing on the same faction in Battlegrounds, ensuring that those playing on your side will speak the same language as you. Please note that not all Battlegroups will be joined into Cross-Language Battlegroups, and this feature will not be affecting the Russian language Battlegroups. We will provide more details on other new Cross-Language Battlegroups closer to the time they will go live.
