Hey Me again!

Bards get Pianissimo to limit their song to one person, why not give COR a JA Called something like "Single Shooter" to do the same thing for rolls? I understand this could/would break cor because of the whole double up chance and busting and what not. But if its the same as pianissimo It would be worth it if it hit the cor and that one other person you select.

What do you guys think?
Too Broken?
Too Stupid?

I'd love to hear some feedback on this.
