Such simplification(2) Set: When your Deep Wounds ability deals damage you have a 3% chance to gain 16% attack power for 10 sec.
(4) Set: You have a 20% chance for your Bloodsurge and Sudden Death talents to grant 2 charges of their effect instead of 1, reduce the global cooldown on Execute or Slam by 0.5 sec, and for the duration of the effect to be increased by 100%.
(Also, I found use for wowwiki - it didn't have updated the set at all )
