one button rotation,opinion?

[Kohashi]

So WoW is implementing one button rotation with slower GCD.
Seems like a good idea to make the game accessible while keeping the skill expression.
Kind of like modern/classic input in SF6.

I wonder if xiv could have this too and then make jobs ratation a bit harder?

I think it's perfectly okay to have that. It will allow extremely casual people and those who have health issues to also enjoy the game more. In WoW, if I am not mistaken, doing Mythic+ while using that tool is just not possible, because the damage difference is just too big. WoW rotation it's proc-based + priority-based, which makes the auto rotation extremely suboptimal, unlike FF14.
