I'm sure all healers know you can change your target mid cast so you are ready to heal the next person. This works great. (also works while dpsing and tabbing)
Exorcism doesn't seem to like it, though. If I am in a mid exorcism cast and target a person who I want to heal next, as soon as Exorcism is cast on the mob it re-targets it automatically. So I am unable to set up the heal on my target. I have to wait until exorcism is comply done before switching targets to heal.
This doesn't seem to be a problem with smite or lighting bolt or wrath that I can tell. Just exorcism. (Yes I have all 4 healers ^_^)
Has anyone else noticed this? Is this on purpose?
