Blizzard will introduce cross-server dungeon grouping.
Eurogamer is reporting that Blizzard will introduce cross-server dungeon grouping in World of Warcraft in a future patch, possibly v3.30 and before the release of the Cataclysm expansion. According to the report, the technology will allow for parties of up to five individuals, however there will be support for larger raids later on, according to Blizzard.
The cross-server gaming will draw players together as seen with the current queue system used in the player-versus-player Battlegrounds, yanking them from the same pools of servers--aka Battlegroups--in their region. "The feature will make it much easier to find "pick-up groups" to run dungeons with, and reward the leader of a successful group," the site stated.
