Why don't we have more DPS abilities ?

[Carighan]

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.

I'd maybe invert that, even. With how everything in FFXIV including tanks and healers is always first and foremost DPS, maybe tie the damage output of healers to healing?

That is, our efficient healers regenerate mana instead of costing it. And just casting our DPS endlessly + using our healing oGCDs would run us out of mana, thus we want to cover some healing by the efficient heals that in turn give mana back to continue casting damage abilities. I'm onboard with making oGCDs cost mana though, and that's an "in general" thing, tbh.
