Numbers within the bars indicate the maximum number of players allowed in the instance.
Following the name of the instance, in parentheses ( ), is a common term or abbreviation used by players to refer to that instance.
/ means only Horde/Alliance players have quests there.
Numbers indicate the minimum level to enter, the minimum - maximum level to queue for the instance using the Dungeon Finder tool; and the level range of the mobs (in parentheses).
Patch 3.3.0 removed the maximum character level requirement for any Meeting Stone, only required that the character's minimum level be 15.
Initially, only level 70s who had purchased a flying mount (or druids of 68 and above, who had been trained [Flight Form]/[Swift Flight Form]) could enter the Tempest Keep Instances.
In Patch 2.4.0 the restrictions on warlock summoning were lifted, and thus those previous players that were unable to enter (unable to fly), may now enter depending on the minimum level for these instances.
In Patch 3.2.0 another barrier to entry was lowered when flying mounts (or Flight Form) became available at level 60.
Since Patch 3.3.0 it is no longer necessary to fly to the Tempest Keep, if the player uses the cross-realm Dungeon Finder tool (the player gets summoned to the instance automatically).
NOTE: All raid dungeons are accessible to both 10-player and 25-player size raid groups with separate gear progression paths in each respective raid model.
