10-player mode

10-player mode refers to the former dungeon difficulty setting (normal mode) for raids, Patch 3.2.0 introduced the new interface (raid difficulty) setting. This setting is accessed from the raid leader's portrait menu; currently the only other difficulty settings are 10-player heroic mode, 25-player mode and 25-player heroic mode for raids. Patch 3.2.0 did away with the old reference, other than showing up in achievements.
