"FFXIV desperately needs a team devoted solely to the role of healers, people who will take the time and effort to make healing fun, and bring back the core identities of the healer jobs" that fits with the game design.

All of the above won't work if someone (or several people) are brought in with good ideas, and are dedicated to healer job design, but it doesn't fit with the other job designs and the way that group and solo encounters are designed.
