Death Knights do have an AoE just like consecrate called Death and Decay - only real difference is its targetted but the radius is bigger than consecrate.

One thing that is messing me up that I will have to fix is I have the talent to become a ghoul when I die. Once this happens I CANNOT use my tank to target anything. I can target the boss but my shamans lose their focus and can't get it back. So, I will have to retalent out of this so I can keep nuking if my tank dies.

I will try coming from the left side today and viewing the camera from in front of me so I can manually target frost tombs and earth shock them as needed.
