Class Hall missions

Introduced in World of Warcraft: Legion, players in their Class Hall can assign their followers to complete missions that vary in duration. Once assigned to a mission, followers become unavailable for its duration and proceed unaccompanied. At the conclusion of a mission, players can learn the outcome by returning to the Class Hall, where a mission report will be waiting. If successful, the report encloses a small reward that generally scales with mission duration and difficulty.

Details
One of the main uses of followers is to send them on missions. Missions are special undertakings which the player can send groups of followers to fulfill, ranging from 2-minute quests to day-long raids featuring a full party of three followers. Successful missions can reward resources for developing the Class Hall, as well as actual player loot usable by the character. In addition, missions serve to earn followers experience, slowly increasing their level and improving their abilities.

Each mission has its own name, follower level (similar to player instances), specific duration, group size requirement, and other characteristics. Players can view available missions through the interface and choose which followers to send on a mission. Missions are specific to the Class Hall feature, and are not related to any playable content.
