I'm well aware that you need to do SCH Quest to get their Ability, I've done those but does it mean I know how to play SCH? Not really... And any good Arcanist will help with Healing pre-LV 30, even a good SMN will pop a few Physick to help the main healer when it's needed so my earlier argument doesn't apply in those situation. I'm talking about the Dongeon mechanic of the SCH, I saw a lot of SMN wannabe SCH that don't even know that SCH is a DMG mitigation job in high lv Duty.
