4.1: Rise of the Zandalari
Dear players,
Starting tomorrow the next Cataclysm content: 4.1: Rise of the Zandalari will be activated on Hades.
What will this mean for you?
Two reworked dungeons, Zul’Aman and Zul’gurub will be available. These instances, which you may know as 10-man raids, will now be accessible as 5-man dungeons. You will be able to queue for them as specific dungeons or by selecting Random Hour of Twilight Heroic in your Dungeon Finder. This adjustment is caused by the fact that we use the 4.3.4 game client and there wasn’t an option to queue for these dungeons through a separate queue in 4.3.
A new quest chain leading to the Zul’gurub dungeon will be accessible. It’s a series of approximately 20 quests and one of the rewards is the companion [Panther Cub].
Guild Challenges will also be available. This feature will make levelling your guilds faster and more fun.
Satchel of Exotic Mysteries will be added. It will contain some gold and a chance to drop gems, pets or rare mounts. This reward is intended for level 85 characters who join the RDF when the Call to Arms is active for them and subsequently finish the whole dungeon.
There’s surely a lot to look forward to 
Hades Team
