Healing spells do not necessarily have to interrupt combo damage spells. They can treat GCD healing spells like ranged attacks for tanks now. Throwing Shield Lob on tanks does not interrupt melee combos anymore.


Also, you can always treat combo spells like proc spells on Black Mage, Red Mage, and Summoner. Firestarter, Thundercloud, Dual-cast, Ruin IV, etc.
