I really want to like this game but in all my years of mobile gaming I've never seen a game so impossible to progress in as this. Rewards and chests are virtually non-existent. Forget legendaries coming out of chests in fact forget chests completely, they're useless what few you get. The meta cards have virtually broken the game already. Once you get to a certain level the game puts you in a downward spiral which is next to impossible to get out of.
