Taking the cry out of crystals
A thought on a non OP way of taking the sting out of opening unwanted champs.
Option - for 6h after opening a new [unduped] champion, you can trade in that champ for a (level-1) awakening gem of the same class.
Example: I pop a 5* Iron Patriot for the first time. Not thrilled, I have a 6h offer to trade him for a 4* awakening gem.
