A summary of healer issues

[Mimilu]

I'd take something like having Stone as the standard attack, then using a non-lily GCD heal gives a buff that turns your next Stone into Glare (Banish on earlier levels?).

Then bring back AeroIII as an AoE DoT while keeping Dia the main DoT maybe?

Would also like Water somewhere too though

I had an idea that might work like this: Have WHM's regular DPS tools be elemental spells, then bring back Cleric Stance as a Eukrasia button that changes them into light spells with debuffs.
An example of how they could work is:
-Stone for single target turns into Glare under Cleric Stance which decreases the target's attack by 5% for 10 seconds. (I thought about having it have a slow effect but then it wouldn't see any use against bosses/raids)
-Aero for DoT, which turns into Dia under Cleric Stance which places a Dia DoT on all enemies with in 5-yalms of the target. (This would work as Aero III essentially)
-Water for AoE, which turns into Holy under Cleric Stance, damaging and Stunning nearby enemies.

They would all still do damage but not as much as their elemental counterpart.
I think this would also fit with the game's lore because light is the element of stagnation and stasis. （*´▽｀*）
