Mitigation style healing appealed to me. Turned out to be really good on SCH so i stuck with it since 2.0. After many many raids and many years later, i have switched to MCH for raids, but SCH i still count as main since it will take a long time to get to the same standard with any other class that i am at with SCH.

Also it is just filthy powerful as a class. Heal, prevent damage, deal damage......no other class can quite match it in FF14.
