So the expansion's been out for over a month, you've gotten all your raid keys done, right? RIGHT? The overwhelming looking raid attunement chart hosted by WoWWiki seems intimidating, but a lot of things turned out to be easier than I'd anticipated. For example, you don't need to complete Shadow Labyrinth, The Steam Vaults, or Arcatraz for your Karazhan key. The Shadow Labyrinth key is at the end-boss, Murmur, but the fragment in The Steam Vaults can be reached without actually killing any bosses, and the one in Arcatraz can as well. The reputation buildup just from doing the usual instances and quests was enough to provide me with almost all the reputation I needed for heroic mode keys, but I haven't started any heroics yet.
How are those keys coming folks? Horror stories with that pickup group in Steamvaults got you down?
