Ever since IO aquired this game from the original dev team, Godzilabs. The direction of the game has shifted to a much more P2W path. One of the first decisions IO made was to sell in-game currency (flooz) at a 4x rate for a limited time event (which is recurrent) thus lowering the value. Second they began selling special event heroes and upgrade materials for cash. Thirdly they raised the max star count of heroes from 7 to 8 stars, invalidating the time older players put in. Pass this game.
