Just give healers a decent damage kit with procs and whatever. It recreates the skill ceiling they've been pancaking down over the last two expansions. It fulfills the (apparent) requirement that healing in most content remains so easy that Curematic Sylphietron 9000 can drag a flagging party through anything. It cures the wasteland of boredom facing anyone who wants mastery of their favorite job. Sorry if you want more healing to do, Squeenix's market research has declared that any healing scenario requiring more than two button presses takes a PhD. At least green DPS is salvageable.
