Working my way through the Shadowbringers healer quests a couple of days ago, and it asked that I put a mob to sleep.

Made me realise I didn't even have it on my hotbar.

I have yet to encounter a situation in FF14 where I have had to put a mob to sleep. Over MMOs, sure. But are there that many situations in this game where crowd control is important?

Casting Holy seems to be a much better way of stopping mobs cause damage since sleep is broken by the rampant AOE anyway,
