Yes, I also get duplicated during the promotion instead of qualifying for the ultimate selection chest. And what do I do? I think you should assume this is what it is just like what I did and other players who got duplicates. And this is my solid opinion that if they bring an opportunity to renew that contract through the use of tokens, it is very unfair why they never provided that opportunity before in the ultimate promotions.
And to clarify i never compared game with casino.
I compare what you intend to achieve: modify the rng for your benefit at a given moment to obtain, as if it were a 100% chance, something that is not. I say what you intend is like going to a casino to bet money and then regret it and ask for it to be returned to you in your hand.
