Patch 2.3 went live. It seems that those slaying the Syndicate in Hillsbrad are receiving Raveholdt faction. Excited about the prospects of additional quests I ran on up to Ravenholdt Manor with my rogue only to find that I was out of luck.
But allowing other classes access to the reputation in conjunction with the new Syndicate rep indicates that more is on the way. What could it be? I am thinking that the story of Ravenholdt will likely be continued in the months leading up to the release of WotLK. It makes sense when you think about it, since Dalaran will be lifting off, as it were, to have an update of the area much like we've recently seen in Dustwallow Marsh. I also remember Chris Metzen mentioning something at BlizzCon about Garona Halforcen and how they would like her to have a role in the next expansion, possibly as a partner for Thrall. Since she was last seen ingame during the closed beta at Ravenholdt Manor, it would therefore make sense that the mother of all assassins would usher in a continuation of the Ravenholdt mysteries. In any case, I know a couple of my characters are going to work on grinding Ravenholdt rep, just in case.
