I'll add my bit in here:

Team:

Druid (boomkin at 40), 4 Shaman (elemental)

RFC: Easy as pie, I did it when I was 15

WC: I waited until I had healing totem for this, 21 I think it was.

SM Lib (@ 36), Arm (@ 38), Cath (@ 41): All cleared, 1 wipe in Lib, a few deaths on the others but no wipes.

ZF (@ 46): Cleared, 3 total deaths, no wipes, all crypts open. Still didn't get all the troll temper. One more go now that I have the mallet on all my toons.

ST: Debating if I want to run this for my lvl 50 quests. I really hate it normally, so I might just skip it and get to 60 for Outlands.
