Multistrike>Haste for Blood
That's what I'll be running.
what makes you believe multistrike is good for unholy? could imagine it being decent for frost but im 99% sure that mastery is way superior for unholy.
besides, are people actually planing on playing frost? its so awkward and handicapped and does so much less damage on plate (and if you are up against a mage good luck reaching him once as frost)
frost is for dogs and versitality scales so bad im aiming for minus in versitality
