A rigid 1-2-3 cycle would be no less dull, as soon as your fingers automate those movements (or one downloads an addon to, when off-stream, automate it for them), but would be tremendously more clunky -- a worst of both worlds.
Compare that, for instance, against a resource gauge whereby each elemental spell WHM casts charges an oGCD spender (all the more usable now that, as of Endwalker, each cast will gives about 1 oGCD of weave-space). You could have a dynamic action which causes successive casts to carry over some upgrading effect to one another until the gauge is depleted or an oGCD spender that grants a further effect (perhaps causing your Stone IV to detonate after formation or Aero II to draw enemies in or the like). While such might, like combos, give additional opportunities that might oblige sequential actions, it'd at least be bankable and choiceful, rather than merely causing you to waste a large part of every trio of casts' effect if you need to interrupt that sequence mid-way.
We have boundless possibilities to draw from to improve healer offensive gameplay, but if there's one direction we could happily skip over, it's rigid combos.
