For talis it used to be that way: Get them for money only first, and make them available some time later. So you can give the spenders an advantage at first, but make some more fairplay and even grounds later on. Would make sense to me to apply the same thing to these characters. But unfortunately this game is getting farer away from fairplay every week. I really appreciate that we have no ads in the game though, but if this is the consequence, I would rather have a video once in a while to generate more income.
