We posted a preview of the Dungeon Journal on the blog shortly before the release of patch 4.2 and you can find it here- http://us.battle.net/wow/en/blog/2943357
If there seems to be missing information, it's because we currently only have the Cataclysm dungeons and raids in the system and plan to add all of the rest of the dungeons and raids at some point in the future.
The purpose of the Dungeon Finder is simply to provide information in-game that is easy and accessible to everyone on the various bosses, their abilities and their loot. It is not there to provide strategies. We just wanted to give a solid starting point and foundation to everyone and let each group determine the best course of action from there.
So theres this new feature, the dungeon journal. Why was it put in? its missing information and doesnt give you any strats, and it seems useful for knowing what loot is on the boss without going to wowhead. why did they spend time adding this?
also is there any way to turn the faces off the big map its actually kinda obstructing my map.
