Let me start off by saying: Why are we losing iconic abilities here? Blood Boil fits way better in a Blood DK kit than Pestilence, which is more of an Unholy ability. Blood Parasites are gone, whereas they provided that fun bit of uncontrolled healing that could either save your life or be of no use at all (some random mechanics are good, Blizz...). And Rune Strike is gone, instead we get Death Coil. So yet another attack (which feels good in the MoP rotation) gets removed to make place for an Unholy ability. Appearantly we'll be using Unholy tanks soon... Ok, that's going too far, but my point is clear. Don't remove key abilities from Blood.
What was wrong with the ability replacement? We could get Rune Strike instead of Death Coil, have the effects of Pestilence included in Blood Boil for Blood spec only (and Pestilence then unavailable for them) and just nerf the Parasites (if you think they desperately need that).
