This may be a little under what you are looking at but a few of my friends will try this soon for Kara. I 3 box DPS. A friend has Prot Warrior and Pally (2 tanks... i know). Another has a Shammy Healer and Pally tank, he will probably spec ret, and the last one has a healer and 3 DPS (he will bring 2), so we have 4 people forming a 10man. Should be a blast
