Alright this is somewhat of some common sense, but some of you may not be aware of it.
After you down Shade, have a druid and a rogue/druid stealth their way to the repair NPC standing outside of the Chess Room. Have everyone walk outside and immediately take a right, standing on the ledge looking at that NPC. Have a warlock hellfire himself to death, get rebirthed and have him summon the rest of the raid.
Some alternatives:
Druid walks around, Paladin DI's the druid, druid rezes paladin.
Druid walks around, hunter misdirects trash to the group, group dies, druid rezes a priest/paladin/shaman, rez up.
