Told on another thread, but relates to this one.

I wish healer design was more similar to how Blue Mage healers function. Of course, BLU healing is kinda barebones, but the principle is there: They heal with Global Cooldowns, and damage comes mostly from an array of OGCDs and filler spells when healing is not needed. Everything costing MP.

Imagining the main healing jobs following those guidelines:
- Spammable damage GCD
- Spammable cheap, but weaker, healing actions
- Cooldown-based efficient healing actions
- Damage based oGCDs
- A couple of healing 'emergency' oGCDs

We could even think how MP could matter again for healers, if everything had a MP cost, and MP replenishment was a mechanic to deal with something more interesting than Lucid Dreaming. DPS actions, for example.
