I don't play SCH in Savage (I'm SMN there), but I usually roll into Expert dungeon with it for queue times.

I prefer SCH as a healer because I literally never have to cast a GCD heal if I don't feel like it. I don't have to take my target off the tank unless a DPS stepped in the bad. It's the laziest healer and I love it so much.

Sure, Art of War one button spam is boring, but it's also satisfying in a way to NOT EVER HAVE TO STOP SLAPPING THE GROUND because the tank is good and the DPS got everything dead enough that I could finish off the final mob with a quick Ruin II.
