New PTR Build 10072 - Changes List - Wowraid
Dungeon and Raid ID Extensions
* In order to allow for parties and raids to progress through instances at their own pace, players can now extend a dungeon or raid ID on an individual basis.
* Existing or recently expired IDs can be extended via the Social tab under Raid by clicking on Raid Info.
* The ID of any instance to which a player is saved can be extended. Doing so will extend the lockout period by the same amount of time as the original lockout (i.e. extending an Ulduar raid ID will add 7 days, a Heroic: Halls of Lightning dungeon ID will add 24 hours, and a Zul’Gurub raid ID will add 3 days to the lockout time).
* An ID can be extended more than once.
* An extension can be reversed on an individual basis provided the player does not do anything in the instance during the extended lockout period that would save that player to the instance.
