Paired up with Convalescence, it can be a nice addition to a healer's cure after taking a lot of damage. It might not do a lot, but if you have acquired a solid grasp on enmity (keeping enmity is a higher priority to healing oneself) and you take a big hit, it can be helpful. It's definitely not something I go to, and I very rarely use it when solo, but it has a niche use that can just make things a little easier on the healer. Especially when said healer is low on MP and can't use an Ether yet (due to recast time).
