Edited: 01 Sep 2020 I played this game when it was first released. At first it was about 60%/40% pay oriented but with all the updates and the developers listening to the players, you can reach top 10% as a free player. You get 100 gems a day(paid cunnrency) which is more than generous than most games. I am in the top 0.75% of the game as a free player all it take is understanding which units work best with what units. I employ rare to legendary units and no mythics and I'm top 1%.
