I think yes healers do have some flash to certain spells, absolutely they do. But each expansion we see an increase to other roles abilities with newer more visually arresting spells. Healers, barring SGE which is new, will get a new animation for their dps spell(s) and some other healing/mitigation spells. While they can be nice most of them aren’t visually satisfying once the new has worn off compared to the other roles.
