I've seen them do it. Not sure why, I'm the kind that nearly constantly is refreshing buffs at every boss myself lol.
Saw a pretty new sch in CT, the first one, earlier this week. Kept saying to my fc members, "Why the heck are they constantly casting Whispering Wind, especially when everyone is at full health?" Got a good laugh at that. Inexperienced healers do weird things sometimes, to compensate for messing up and stuff I've found lol.
