That's a question that will yield you as many different answers as there is people. Not only is it subjective, but the feedback will also be dramatically coloured by a lot factors like, in what actual content the players go through and base their opinion on, what level of play (meaning, skill floor and accessibility, skill ceiling and skill expression/optimization?), etc. Just having a proc system makes it more confusing and less intuitive to order a rotation properly for a new player, but that doesn't mean that the actual rotation at endgame level is harder. That doesn't mean that its execution is harder, because then you run into loopium and burst alignment shenanigans and not all jobs are equal there too. Then there is uptime considerations, and for some jobs like monk (optimal drift, double solar, etc) and black mage (transpose lines), actual advanced optimization is completely out of this world.

And one of the biggest, if not the biggest factor is that people will by definition rate what they main a lot lower than the rest because they have countless hours of practice behind. Some will rate it higher than it actually is out of bad faith as well. It's... well. I hope the hidden message of such a thread is really to show that it's pointless.

You'd really need a lot of finer filters to rate them and put people somewhat on a the same page/context. Well I guess you said optimally, so it's on me to diverge I guess.
