One place it has a use is the S rank Agalope during Seductive Sonata, which forces players who are too close to march into a melee range one-shot.

The funny part is quite a few times when we have multiple healers and one guy gets caught, we all seem to go "finally, our moment to use this ability!" and the poor player gets ricocheted around the area like a tennis ball between several healers. I've seen up to a 4 way chain so far. Fun times.
