I have been playing this game for more than 3 years, level 76. Since I have stopped paying and buying gems I haven't received any decent heroes. They say the heroes are selected randomly, but in my personal experience it looks like it is all about the money. Stoppe enjoying the game now, Valor pass is a scam, it used to be once in a while now it is there almost every other month. So, in short, it used to be a fun game but now it is not.
