Unfortunately we don't do the whole "here's the untested spec I'm going to use" posts. If you have a new spec you think is better than the best recommended spec, feel free to test it. Then post it with the test results and your reasons why you chose what you chose.
With a blood build and always having those 1-2 floater points that never seem well-spent, I think post IT buff I'll be using this spec (I miss the human racial on my new Orc DK tank). 53/11/7
(we always have an Enh shaman so Abom's Might isn't needed).
