The damage is..almost a 1shot for me.
The second hit is 480,000 damage before any cds. We're having a great amount of trouble with it - I've been saving my Guard for the second Unrelenting thing each time, but even with shuffle, and Guard I'm still taking ~60% of my HP from 1 hit. Our 2 healers are just having a lot of trouble keeping up if the raid is taking any extra damage...
Is there a way to reduce the damage, and if not how are other Monk tanks handling it?
