I have only 400-ish AA's. I've maxed out the double attack aa's and Vanquish Undead aa's. This weekend my guild was back-flagging in Inktu'ta, and I tripped off my Intensity of the Resolute veteran AA on poor ol' Kelekdrex. A guildy parsed my dps at 741 average for the fight. I lost count of all the 8K+ slays and dozens of lesser slays. Even the monk in my group was amazed. Next highest melee dps in the raid was a monk at 608. Even the paladins with Redemption and VU3 got smoked by the damage I did in that encounter.
With this weapon, and Enraging Blow augment, Shield of strife, and Boots of Dispair, Aggro is a LOCK. All you tanking paladins need to get this hammer.
