Eh, it is a bit complicated to talk about accessibility. There is a bit of a design mistake that happened in FFXIV where the mechanics got attached to aesthetics, which is a dangerous thing to do in any game since it means that players who want to be the gunman are stuck with the mechanics linked to the gunman, including the baggage that goes with it. Machinist is a very fast paced job and it isn't suitable to every player, but would you go tell that player that he can play dancer? He wanted to be the gunman, and he probably doesn't like the whimsy of the dancer. It's the same thing with monk and other jobs.

And by no means am I saying Machinist and monk are unplayable: They are playable jobs, but they aren't right for every player. Those players that DO like the current version of that job would obviously complain if it were slowed or simplified. But these sort of details also impact accessibility, or the perception of it, because ultimately accessibility is a factor of the job one plays and the content it is being played in. That's why when I was advocating new addons to make savage more accessible, I never brought up something like nerfing the speed of jobs while in savage. Right now the only thing they can do is give better learning tools to help overcome the issues people face when using more complex, faster paced jobs, simply because it is what they wanted to play aesthetically.
