Why do people even have it on their bar? Swiftcast, esuna, lucid dreaming are must haves. Surecast is increasingly a must have, to be able to ignore knockbacks. Largesse, clerics, and even eye foe eye would have more use. Rescue is only more useful than break out of the role actions, and that's assuming you have a great connection, the person you want to rescue is in range, and its something that would outright kill them. It's hard to see it being much of any use.
