Extremely P2W. The game is fun in the beginning, but it quickly starts to take weeks, sometimes more than a month, to get the necessary ascension items to increase a hero's level cap. Same goes for weapons. So you'll quickly get stuck at fights you're too underleveled to beat and then spend a month grinding to progress, only to quickly get stuck again five fights later. Unless you open your wallet, of course. The game has no ads, but is riddled with "limited time" offers for IAPs. Edit after response: Why can't you "take note of my feedback" here?
