World of Warcraft's site has been updated with a new developer post to introduce players to a new feature coming in the forthcoming v5.4 update. Called 'flexible raids', the feature will allow smaller groups of players to participate in raids. In particular, Blizzard is targeting social groups (friends & family) and smaller guilds.
The Flexible Raid system is designed so that the challenge level will scale depending on how many players you have in the Raid. So if you switch between 14 players one week and 22 the next, the difficulty will adjust automatically. Keep in mind that unlike Raid Finder, no matchmaking is available, so you’ll need to make sure you invite people to attend—but if some can’t make it, it’s not the end of the world (or the Raid). You’ll also still be able to invite Real ID or Battle.net friends cross-realm. Who you choose to bring and what Item Level gear they’ll need to join your merry band is up to you, too—there’s no Item Level requirement for this Raid difficulty.
