The game is very fun, but it gets to the point where you can't play casually. It treats F2P players pretty well, but you have to have certain units or specific teams to beat certain content such as clashes or coliseums. The grind is kinda harsh as the drop rates for raid characters/ evolution skulls are terrible unless you are playing the hardest difficultly which are almost impossible to beat if you are a casual player. If they lessen the grind, I can give them 5 Stars.
