Earthquake card vs. other tanking trinkets
I've been making a lot of Darkmoon cards, and managed to grab enough to make a Darkmoon Card: Earthquake. The dodge is undeniably nice, but I'm really unsure of the value of its on-use in Cataclysm content. Can it essentially be treated as a 11500 heal?
Just for reference, my current trinkets are Lifebound Alchemist Stone and Impetuous Query, although there are several easily obtainable upgrades to my second trinket, so something like Throngus's Finger or Porcelain Crab might make for a more apt comparison.
Would you sell it, or use it? (I'm a Death Knight, although it would be interesting to hear about how it might be more or less useful to different tank classes)
