1. Make it refresh all motifs when you activate it, or;
  2. Whenever you cast a Coda while Virtuoso is active
  3. Make it give you 5 combo points on your current target (perhaps with a 20/30m range)

Any of these three, really.

This would mean that you could use it whenever, without needing to refresh motifs first. Would make it much more useful.

I'm getting more in favour of a radical restructure of Bard, but this would seem to be a fairly simple, and non-imbalancing change that Trion could do whenever. I'm pretty confident they won't change anything, but it doesn't hurt to keep prodding them until they do.
