I have a question about Deep Coruption stacks. My raid group has recently killed HM Yorsahj. We use the same set of healers each time; Hpally, Rshaman, and Dpriest. Last week we had no problems killing Yorsahj on HM, however this week we ran into a few snags with Deep Coruption. This week our tank seemed to be aquiring stacks due to the shaman's Earth Shield.
I have read from multiple sources that Earth Shield is not supposed to add stacks, however we died 4-5 times because of Deep Coruption stacks on our tank (a few attempts no healer threw a single heal on him.) We did finally kill him after the Tank removed Earth Shield during each purple phase. Is this a bug, or is Earth Shield supposedd to add stacks?
