A few members of my FC and I were running WoD. I was on heals and the other healer was in cleric stance almost the whole run, kept running out of MP, didn't avoid AoEs, and then during the last fight was too busy arguing about grammar to actually heal. The raid wiped and we kicked the healer, and the healer we got in replacement was on the ball and we finished with no issues. At one point the kicked healer apparently had made a remark to me that "cure 2 is a thing" (I didn't see it) but then I realized if they were just spamming cure 2 instead of cure (cure 2 with a proc) no wonder they were constantly running out of MP.
