Raid difficulty is a setting controlled by the raid leader that determines the difficulty of the encounters for 10-man or 25-man raids. There is a Normal mode and a Heroic mode for each size. Warlords of Draenor introduced Mythic mode 20-man raids.
As of Warlords of Draenor, Flexible Raid mode was effectively replaced by a flexible Raid Finder mode. Burning Crusade raids only have fixed 10-man or 25-man sizes and 20-man Mythic mode introduced.
As of Mists of Pandaria Patch 5.4, Siege of Orgrimmar also allows a new Flexible Raid mode that scales in difficulty depending on the number of players from 10 to 25. Drops will be better than Raid Finder, but worse than 10-man Normal mode.
- All raids introduced before Patch 3.2.0 will use 10-player Normal mode for the former normal mode (10 man raids) or 25-player Normal mode for the the former heroic mode (25 man raids).
- All newer raids beginning with the Crusaders' Coliseum can use the 10-player heroic mode and 25-player heroic mode settings to access harder versions of the raids, not to be confused with hard mode actions/events within the same raids.
- Blizzard has made this insanely complicated by changing the composition of raid modes with almost every expansion.
