New Feature: Virtual Realms
Virtual Realms are sets of realms that are fused together, and will behave exactly as if they were one cohesive realm. Players on the same Virtual Realm will be able to join guilds, access a single Auction House, join arena teams and raids, as well run dungeons or group up to complete quests.
Players belonging to the same Virtual Realm will have a (#) symbol next to their name.
Blizzard is finally taking steps to help low pop servers :O
This + The flex raiding, I can see Muradin raiding scene flourishing again :O
