I started healing fairly seriously as a second job, normally a tank, since I unlocked scholar and love it so far.
I've found in at least the very early content I just live in cleric stance while healing and don't even think about. The 1st moment I turn it off is Haukke manor's final boss as a safety cushion till she's 30% and then flip it back on to finish burning her down. Brayflox I have it on during all trash and off during bosses till they're down to 20-30% and help speed up the final burn down. Haven't healed anything higher yet.
Is this sort of use of cleric stance normal for that level of content, and what is the community advice on when/how to use it?
