It looks like Blizzard finally put together an encounter where the key focus is on the healers.  How much focus is on the healers?  I think this quote from WoW.com sums it up nicely.

“So while those classes are the ones I would suggest going in, reality says though that you should send in your best players. Yes, send in those players who will do everything in their power to not let those stacks fall off. If they can manage that, then they’re gold.”

That’s not to say that the tanks and DPS are sitting around doing /dance.  There’s still a lot going on outside of the Emerald Dream.  We noticed that the adds do not spawn evenly so having the DPS know when to assist the other side was critical to the success of the encounter.

The faster you can bring the adds down in an orderly fashion, the easier the encounter is.  Every little bit helps.  For example, Nachtung runs up and bandages Valithria at the start.  That’s roughly 2300 less healing that the healers need to do.  Teamwork, that’s what it is all about.

You’ll notice in the screenshot that there a crazy moonkin (Chizzlechest) trying to get on top of the chest.  He did manage to finally get up there.  We would have tried to help him, but he’s already playing a moonkin so it’s probably best just to leave him be.
