Last night I 4-boxed shaman with 3 guildies (druid tank, pally healer, mage) in Kara. We did everything but Netherspite in 2.5 hrs. It was so easy mode we laughed the entire time. Prince only got 2 elementals, Aran never got to his elementals, and Curator died during first evocation.

Here's the kicker, my shaman just hit 70 and are in quest gear. The other 3 are T4/ZA/Badge gear.
