What's the best way to use signature stones?
I have a bunch of generic signature stones accumulated that I know I should be using, but I've just been so indecisive about the best use to get max value out of them. Most of my 3* are duped and I have a bunch who are approaching max. For 4* I've been saving both class and generic for specific Champs I am waiting to dupe. And, of course, none of my three 5* are duped. So while in my case the question applies mostly for 3*, others may face similar dilemmas for their 4* and 5*.
