It honestly feels like the Meditation 60 ability SAM got or the GL one MNK got, except support centric as that's the DNC identity. I've been maining DNC since early access and agree finding moments to capitalize on the ability is difficult. It requires communication and coordination with your party to get the most out of it.

I'm fine with it being a capstone. DNC is a support DPS and you get Esprit and Saberdance just before it so I appreciate a hybrid support DPS skill, without inherently dealing dmg itself. If they buff it, I'd like a support buff personally. Maybe give it DR to everyone in it, making it more attractive to stand in, or reduce or nullify mp costs of allies in it. Actually the latter sounds downright op compared to maybe 10% DR.
