Where it's all about luck, there's not much the player can do. He can walk away from the Inventor's coalition smiling from ear to ear, or he may want to smash his PC to a million pieces. Anything that introduces and encourages an addictive gambling type behavior is not going to be positive. At least with the Airlixir system, you know where you stand with progress, and you know you will get there regardless of RNG.
