A friend of mine occasionally likes to try to play around with it and see where you can use it. In most situations you just straight up can't. The devs put sleep in the game and then forgot about it entirely.
The only place in the game I can see sleep being somewhat useful is if you solo PotD on BLM, but that's such an edge case it really doesn't justify the skill staying in the game.
