One word, awesome.

Tanking cadeseus is now a cake walk with everybody doing their jobs correctly on turn 1. I can easily survive as a war up to 5-6 stacks as a Ilvl 83 war, before I would get oneshot at 4 stacks. I'm going to see in turn 4 if I have to kite anymore, but I probably won't.

There are some fights where I prefer to off tank like turn 1 ADS, but I'm no longer a healer nightmare to deal with.

Steel cyclone is awesome, It saves me TP when I really need to go to town on adds. And the new vengeance is totally worth it.
