This could have been a great game, if only the developers were not so greedy and pushy. They clearly spent more time monetizing the game rather than making it engaging. There is no story, the campaign is just a power-creep to force upgrades. Gameplay itself is monotonous. Way too many ads and sales notifications everytime you login, or finish a level or level up your character. PvP is blatantly Pay2Win. Even if I choose to pay, it's way too expensive. There far better games much cheaper this.
