I'd agree, technically you could use it, I have but it's used so infrequently I qualify it as "useless in most content/if your team is undergeared/if your team is not yet competent (skills, mechanics issues)/are in relevant content/there are no better skills available to use"

I have left in on my bar for my "just in case" scenario, but it's left in a dusty corner just like cure is.
