GameSpy - Other major additions to the game include raid functionality and new travel options. Raid groups are large parties of players (up to 40 in this push) who work together in instanced dungeons to accomplish massive challenges too great even for high-level normal parties which are limited to 5 members. Unfortunately, raid functionality hasn't been matched with an influx of raid content and there have been indications from Blizzard that they may hold back the big raid content (large dragons and such) for the release and may not allow beta players to see it at all.
