I like it because there's no long sequence of spells you can fumble and have to start over. It's just "what is the current state of my current mana bar and procs?" and go from there.

I feel like it maps well to one half of a controller if you put the four basic spells in a square.

Stone Aero

Fire Thunder

Tipped diagonal on a controller of course, but that's the idea. You're either crossing to the opposite point of the square or moving left-to-right (or casting Jolt/Cure/Swiftcast on the other half of the controller to get things started).

And the melee rush bit has a nice flow to it that arranges well on the controller too.

It sounds like Endwalker's job tweaks will mean we have a bit more freedom to hold off on using the melee combo if it's currently unsafe to go in, instead of hitting the awkward point where any more spellcasting will overfill the bar and ruin your chances of triggering a proc from Holy/Flare.
