On our first night of pulls, we got it to P3, although i'm sure we can do it better, specially in the intermissions. I'm still not sure what raid composition i'm gonna use... currently we have:
Tanks: Guardian Druid / Prot Warrior
Healers: Holy Paladin / Disc Priest - Mistweaver (bench)
DPS: Affliction Lock / Destruction Lock / Boomkin / Elemental Shaman / Enhancement Shaman / 2x Rogues (Combat - Sub i guess) / Retribution Paladin
About the intermissions, i'm sure there a couple of tricks we can try, like the 4 pack pulling, etc. Any tip for the fight is greatly appreciated guys
