Holy Priest has
- spammable filler spell (equivalent to Glare/ Broil/ Malefic/ Dosis)
- dot (equivalent to Dia/ Biolysis/ Combust/ EDosis) but only about half the duration
- Holy Fire on 10s cooldown
These 3 already provide a more engaging dps rotation than any healer here has because of the shorter duration of the dot and the short cooldown of Holy Fire.
- Shadow Word: Death on 30s cooldown
- Holy Word: Chastise on 60s cooldown with a cooldown reduction through Smite casts
While the latter isn't used on cooldown in raids, it definitely has a more engaging dps rotation than FFXIV healers.
The talent skills also deal damage although they're generally used or even kept on cooldown for their healing.

You can say what you want about WoW but healer dps rotations are in a much better state than in FFXIV in addition to healing being generally more intense and requiring decision making over planning. There is a reason for the many healer threads with some of them reaching 100+ pages. It IS an issue and it is something that WoW still does better. From leveling dungeons to endgame raids.
