As someone who primarily plays WoW at a somewhat high enough level (Mythic raids cleared each tier with plenty of time to spare on farm) and is a casual andy in FF14 that also looks into and learns optimal ability usage, I find it personally refreshing that FFXIV's got a somewhat defined rotation, albeit the job i primarily dps with is Samurai which has some choice in it's abilities pressed if you wanted to start on the flank or rear after sending a Midare mid fight pending where you'll be positioning according to mechanics so playing it doesn't exactly feel like im playing it the same every single pull of a fight itself. I'm already pressing a similar amount of buttons in my baseline rotation as i would be in WoW to feel content enough in the actions used.

RNG abilities in terms of resets/procs won't really work well at all with FF14s current combat jobs and would need to be build from the ground up. They'd need to firstly set-up a bunch of cooldowns on 4-5 rotational abilities, which you'd just press based on whichever has the highest potency in FF's design which would then kinda stem back to the same static rotations.

I also feel like the hyperbolic 60 action 'rotations' that people post to 'memorise' or they're trash at their job are pretty damn silly and just overcomplicate things to make them sound smarter than they are as there are much better ways to learning the FF14 Job rotations, for melee which mostly stem from, put up buffs/dots and spam your highest dps combo.
