The fact remains that there ARE mechanics that need to be cleansed sometimes and what happens when you run into it with healers who aren't running it for whatever reason? The first boss in Dun Scaith for example inflicts doom occasionally in a pair of party members. Death is avoided simply by cleansing it.

Either way I felt it entirely unnecessary to make it cross role when it was right there on all healers' leveling lists, then removed to be made cross role with absolutely no compensation.
