At least in XIV case MP is not the cause of the problem, the excesive homogenization of both dps and heal tools are, especially the dps rotations as we end up pressing the same button hundreds of times more than any other.
Sage is none of that, it falls under the same 1 button spam as all of the healer and its gimmick of "complexity" in the form of eukrasia is very underplayed only working with the standard nuke to give us the standard dot every healer has and with the 2 GCD heals that barely see any use to give us their upgraded version a la Physick->Adlo, there is nothing unique or special about that.I do think that Sage is an early glimpse into the direction that healers will eventually change into (more buttons to press to complicate DPS rotation and healing options)
We like both, as simple as that. Most of us come because we like the support style and are right now asking for more dps options because increasing the healing requirements at this point would require a game overhaulThe thing all healers need to come to terms with is what are they actually enjoying doing as a healer. Do you want to spend more time doing healer things or do you want more time to DPS?
Then they're failing, healers after the changes have become the least played role on all level ranges and that excuse of being critical is moot when content has been proven to be clearable without healers, we're a comodity not a necessity, and for the endgame (where this would matter) due to enrage timers dps are as important as the other 2 roles so that argument could be applied to them too. There is no justification for having an ENTIRE ROLE with the same gameplay of 1 button spam.Also keep in mind that healers and tanks are very simple for a reason. They're critical roles and the devs don't want to complicate that, which would result in less people playing them if they did.
