Just because the name says "healer" doesn't mean the role is made to just heal and it would be great if the game was more open about it.

Damaging and non healing actions that benefit the party (buffs,CC...) have always been part of the role simply because the limited utility heals (as hp is binary and damage taken is a limited resource) and any decent healer can attest to that. In XIV, a game with so many dps checks that can't be cleared without healer dps, a game scripted in nature that has been built with the idea of healers dealing damage, disregarding the non healing side as something "not for healers" is a mistake as big as saying that dps shoudn't help with mit or tanks shoudn't deal any damage.

This reductionist view of X role should only do Y only hurts the playerbase. It grows lazy players that refuse to see the big picture of a fight and limits their usefulness, because, no matter how they try to spin it, a healer that keeps the party alive and does damage will always be more useful than one that don't.
