I assume that golden keys have some minimum quality level but not sure what it is. I had erroneously thought you would get 1 legendary but after opening one finally that proved untrue. Does anyone know how the keys work with regard to the rewards? Is epic the minimum quality you can get? What is the chance for a legendary?
Also, as a side note…is there any reason to hold onto these keys until later (like after DLC is released)? I know waiting until 50 is a good idea but not sure if I should just save these until later or not.
