Edit, April 9th: In light of the RPPM changes and sim improvements for DKs, the lists previously shown here became somewhat invalidated. Rather than trying to maintain them here, I will simply point all of you to the EJ threads for Frost/Unholy DKs- the guides there will soon be updated with appropriate BiS lists (and keep in mind that things can and will change in 5.3).
For now, I'm removing all links to my previous BiS lists and asking for this thread to be locked.
