Never had issues with a SCH healing Brayflox or Cutter's Cry as long as they were paying attention to what they should be doing. What I have seen however is in AK and WP, the SCH's don't like to even use leeches often.

On a sidenote, the only issue I see is the Fairies dropping on the 1st and Last Boss in AV. I wouldn't mind seeing fairies receive AOE Resistance or Immunity. But even in AV, a SCH can heal it no problem if they pay attention. Course paying attention and positioning for many DF healers is a problem. But a problem they simply need to fix themselves.
