There's one issue I can see & that's people who are on ACN/SCH or AST & either haven't levelled CNJ or don't have Cleric Stance cross classed. It's unforgivable in my opinion but then again I'm a DPS SCH so healing is my secondary function. It's one if the perils of being able to reach lvl60 in PoTD with a class you know nothing about & might never have even used outside it.

In PoTD my fairy does the healing except when someone doesn't pay attention & gets into the danger zone, then I step in. XD
