I use it when tanks pull mobs out of the floor AOEs that ninjas or summoners put down, pull the tank back into the floor puddle so the mobs follow.

But I do think this is a skill that would be better FOR tanks, but to use on enemies. Something that will let you pull caster types into the pack of all the other mobs.

As far as a new healer tool, maybe Float? Something that will pull a party member back onto a platform if they would fall off?
