These seem to be the issues that SE attempted to address with the revamped Lily system in Shadowbringers. WHM got two new instant-cast GCD heals, Afflatus Solace and Rapture, and a big damage spell, Misery, that "refunds" some of the DPS lost due to GCD healing. I'd say this solution has been fairly successful. I know some people still complain about WHM's lack of mobility, but the job is at least more viable than in Stormblood.
