Excellent game-mechanic with lot of heroes and diverse skills. Beautiful & interesting graphic & sound. Only 1 problem: RNG. No paywall of any kind, only pay to progress faster. But with each update they try to slow us down. E.g. challenge gave fixed silver, then RNG-base came, got AVG 750K loss/week. Today's update even lowers the minimum from 1M to 410K. Battle strategy, core of this game, is useless because actual dodge/critical don't match the stat. Again, RNG. Don't play this game!
