when I replace Demonology with Destruction in your link, it shows that darkmoon card is higher dps than everything other than Will of Unbinding......even heroic cunning & insignia.

this has to be flawed, there's just no way DMC is still that good.
My warlock is destro and I'm using 390 will of unbinding & DMC......but I was hoping to upgrade to cunning or insignia. According to that link I shouldn't even upgrade.
