Emerald Nightmare Released

Emerald Nightmare is currently available on Normal and Heroic difficulties, with Mythic and the first wing of LFR opening on Tuesday, September 27th.

For strategy videos and the release dates of the remaining 2 wings of LFR, please check my Learn the Fights: Emerald Nightmare post in the Raids forum.

What ilevel are we talking here? 825?

Just a guess, looking at relative ilvls and requirements for heroics & the standard guidelines surrounding transitioning from Heroic Dungeons into the first raid of a given expansion, I'd say a reasonable ilvl requirement for Normal difficulty would be somewhere in the 820-825 ilvl neighborhood. PuGs, of course, may require 830-840 ilvl though, as it is reasonably obtainable if you put in the effort (read: have no fucking life and get lucky).
