BE WARNED!!! When you reach a certain rank, where you will be investing a lot of money and time, the game will force you to get 8 characters that requires a lot of resources to buy. Especially if you mistakenly used up all resources you have, like gold, gems, rubies etc before reaching to that point. And each resources are not paid cheap. You can't play rank matches once you obtain 8 characters. Even emoticons are being sold in game lol 😂😂😂
