See, the thing is Blizzard really let's all this "delete priest" nonsense get to them. The people who scream delete priest really are a vocal minority in the community. So blizzard feels like they have to nerf priest to satiate some of these people. Is hysteria a strong card? Undoubtedly. Is it completely op in an op class that is nerfed almost every patch? No way. People just dont want to play around it.
