I found this handy link somewhere on Curse gaming. It has most classes represented, so instead of spamming the forums over and over, I'll just hand it to you here.
Summon Stone is amazing - Skullflowers (DK in Midwinter, wrote the Unholy/Frost DK guides) wants this to be Icy Veins but better, and once all of the spec guides are up I think it will be that and more. I wouldn't be surprised if it ends up being the successor to Elitist Jerks.
