Fun at the start then turns into complete garbage with extremely high requirements to get far in the game. Worse than the average pay to win games. Could have been so much fun but just too hard to level up heros. Too hard to get the same good heros to progress them. Summer rates are probably in the negatives. Very sad to see. The responses from devs are typical cut and paste to each rating. Hoping this game just vanishes like it deserves to.
