I don't think we need another Fairy, however I think Fairies should be overhauled such that one compliments our shields and the other compliments our healing. Through this, double SCH parties would be slightly more feasible as double AST parties are.

I don't see how SCH should be relegated to "off healer" especially now that all 3 tanks have been relatively standardized such that any can MT or OT effectively. That said, why not standardize all 3 healers so any of them can be a Potency Healer or Shield Healer depending on stance (or in SCH's case-Fairy).
