I think SCH is actually inferior in some situations Times where your cohealer dies and you're left trying to heal through an AoE and intom is on CD, you will be screwed. AST/WHM can spam medica. SCH can't. I have wiped countless times in progging savage content(esp o4s) from that exact situation. One emergency tactics isn't enough and succor heals for far too little and has way too high an mp cost. Other than that I'd say sch is pretty okay.
