Been playing over a year. Enjoyable game, at first 5 star. The 2.99 subscription card allowed to level up at a decent pace. But now there are 4 subscriptions that total 12.50 a month. Price up, but leveling speed down. Cannot remain competitive. But the big problem is balance. UCool regularly releases massively overpowered heros that you need to pay for. By time an average spender can get they nerf and release a new one. Costs steadily rise.
