The Nexus

Whatever the Blizzard art team is being paid, double it. This place is beautiful. I've been through once so far and almost paid more attention to the scenery than the mobs!

The group I was in was 4 AIE-ers and a pugged healer. We did very well wiping once on the Tree-Shaper and twice on Keristrasza. Not bad for learning the bosses. I'm not sure if there is some way to avoid being thrown in the air on the Tree-Shaper. We just powered through him the second time.

The key to the Keristrasza fight appears to be making sure you move (or at least jump!) to clear the Intense Cold debuff and dispelling Crystal Chains quickly so that you can move. It's a magic debuff so that mean you need a paladin, a mage, or a warlock with his felhunter out. It's probably possible to go without one of these but it may require a second person who can heal.

I also picked up Greaves of the Blue Flight so definately not a waste of time.
