that's sound realy impressive^^
I test it by my own in the new 3 heroics yesterday (raid is tomorrow) and revengespam is amazing. I run with my normal specc 15/3/53 and only a dps mace (http://www.wowhead.com/?item=47973) and trinket (http://www.wowhead.com/?item=50342), the other eq is normal tanking stuff. The performance was very nice, spamming revenge, cleave, hold thunder, slam and shock on cd. I pull 5,5 - 6k dps on 3-4 mob groups and did also 12k revenge crits. On group revenge has normally 100% up, because of the many hits. So in my runs yesterday i had normal geared dd's and they pull around 6-6,5k dps on this groups and i don't have to tab any target to hold aggro, they all glue on me :-) and that's form the beginning of the fight with bombing lock and hunter. I think is a very nice change for warri aoe tanking, i will only miss the old revenge on my pvpprot, sometimes.
