Getting refused to EX groups as a DRK

[Abbul_Stonecleaver]

So'sanuwa/Ul'sanuwa in Bis EX just hit like a truck. They frequently cast Tidal Wave/Dry Fin, which hits for 6~7k unmitigated, and do 1~2k-ish autos, on top of random 800-ish damage from Vacuum Wave. Fortunately, they don't do any of this while casting Dead Water and once this phase is over there's very little tank damage going out for the rest of the fight.

I find tanking the pair of adds in last phase to be way more brutal than the snakes. On my first clear, I went full Vit cause I felt so squishy.. I got up to 20k hp. Full time Defiance on them. I ran out of CDs and still died at 20k hp. It's mostly when healers have to handle the things (dragonkillers?). Last night I only picked up lone add thankfully, and the Drk died in the same spot. He also lamented how painful that part is. No one else seems to have issues though there it seems.
