I once liked this game in the beginning, but now it's just pay to win. There's no balanced system. If you don't have good cards or heroes against pvp then you just loose. Those cost diamonds which don't even come as often and are relatively poor. You have to have luck to win this game and only the people who have most just keep getting better while the ones who don't stay playing the game for a whole year to get a legendary. The whole game will get adventually frustrating.
