I finally got around to attempting an instance after questing to 33.

Team: Prot Pally/Holy Pally/Mage/Mage/Mage

SM: GY - 33
SM: Lib - 35
SM: Arm - 37
SM: Cath - 39

Went rather well considering my epic fail equipment (mages still wearing pre ghostland robes)

Of course I get the Ravager first Armory run when I seriously stealthed to Herod over 30 times with my Ally druid and summoned my Ret pally without it dropping.
