Do to the fact we dont always get tanks who know how to mitigate properly.
As a WHM I look for Suprana's friction, when I see it I will swift stone and Eye for Eye, and Virus garuda when she is back, and Bene or timed DS Cure 2 spam as soon as first big chunk is gone. Providing the tank geared well enough, this should carry a braindead tank through this phase.
