A predatory game forcing you to buy stuff to remove ads. Be prepared to watch ads after every match. The company will tell you that the ad revenue helps keep the game running smoothly, and I myself bought the cheapest possible option to remove the ads. Great game from an otherwise greedy company. Also, balancing issues. This game will outright match you with players with overpowered characters, once you're on a loosing streak they will unsubtly suggest you buy their legendary characters.
