Healer are no longer Healers we are DPS

[Liam_Harper]

I wish in FF my worth as a healer was based more on how well I can keep the party alive, rather than how little I can heal and how much dps I can dish out.

This is a misconception.

It's not about how little you can heal. It's about how efficiently you can heal. Since overheal is completely worthless and oGCD's are mostly free, it makes sense that you try to cover the necessary healing with oGCD's as much as possible, with as little overheal as possible. Then, since dps is always useful, it makes sense that you try to fill in every bit of the downtime you've freed up with your efficient healing with dealing damage.

Your worth as a healer is based on how useful you are and how much you contribute to the party. Any inexperienced sprout can just spam GCD heals and keep the party alive, but playing efficiently while dealing damage takes planning, coordination and knowledge of your class, your toolkit, your co-healers toolkit and the encounter.
Even if they increase damage taken so we have to heal far more, the efficient healer who can deal damage too will always have more value.
