The progression system is awful,everyone you play is AI so the computer has control over all your opponentsIt cheats me allways,and you also play against AI characters that are not avaible to purchase in the game meaning the compuuter can give your opponents any abilaties they want.You have to get loads of shards just to unlock some characters who will be at level 1 when you get them at least at level 80 and the only way to win is to spend real money and it made 2 different accounts so I lost 1
