Not sure what you mean, I feel I have been pretty clear on how I do it.
So it goes something like this;
- Boss casts Double Swipe.
- I Barrier for when the Swipe is over (He will cast a triple puncture and 1-2 melee swings at the same time. 1 Barrier should be enough to mitigate it with that much vengeance)
- I use Block shortly after to mitigate the melee swings before the next puncture. I start pooling rage again.
- He casts puncture without swipe, but its not bursty enough to cause problems
- The last few melee swings I take without anything, you will have a gap while hes casting Swipe where you can be topped before the big hit.
- Boss casts Double Swipe (Repeat)
I hope that helps
