I absolutely love heavily armored healers, something Final Fantasy has always lacked, to my knowledge. I've always been drawn to them, and they've been a staple of western RPGs since early D&D. Usually they take the form of a paladin or cleric (or in WAR's case, Disciples of Khaine OwO). And I think it'd be sexy as hell if FFXIV set a new precedent for the series and gave us an armored melee healer.
On top of that, we just need more healing jobs period. So who else wants to heal people while looking like a hard-ass?
