Drop Bloodcraze, Drop either Imp.Rev or Thunderstruck (or both) finish off Deep Wounds, finish off Incite, pick up Cruelty,take Safeguard if you want to help out the other tank with Impales. If the healing is too much on Deathwing, you need more DPS on what 's killing you.
What Tengenstein said pretty much. Warrior Tanks are still speccing into DPS talents for the same reason we've been speccing into DPS talents for the whole of Cata. More DPS = less time the healers need to spend healing. That and Blood Craze is purely RNG, which i guarantee you won't proc when you need it 9/10 times, but it's worth less than a health pot anyway.
