CC in other games is frequently used against patrols or adds which FFXIV ditches by having virtually no patrols, and no patrols of consequence that I'm aware of.

I've used CC to great effect, to save a party in other games, but the need is created by the content designers. Since most of the dungeons are also linear corridors with no options, no patrols, no real choices you're not going to need emergency tools since we have such perfect control over exactly how many mobs we engage. Even in the overworld it's virtually impossible to get into trouble outside some of the earliest ARR zones because mob density is so low that they rubber band back to home positions if you try and pull too many.
