To a point I agree , its still a tactic that can be used an itsn't useless, i pointed out blm just because of their aoe sleep vs whms situational single target sleep. If im healing a Squishy tank or a tank pulling more damage than im prepaird for or geared for, i'll use any options i have to help. For what reason it may be, Stragger , tank losing aggro on one mob, If i have to use FA to get it away from me i will but i will also swiftcast sleep on it aswell , Sleep lasting longer than the bind does, what the tank does from there is up to the tank. What i am saying is Sleeping FA or any other spell is very useful , its only a matter of how an when it is used an who is using it. Only a healer can make the call at that time, just as with CS dance between dps an heal. I hardly use Sleep , an never use it in CT or ST But i could see how it can be used (on some mobs) as another interupt besides silence, stun.
