This game has some really big issues 1. It is pay to win 2. Diamond characters are way too hard to get 3. Some characters are bugged 4. Progression issues such as rewards don't get any better as you progress e.g. either you win battle 18 or battle 180 in a tower it doesn't matter cus you get your reward from the same pool 5. It's so grindy and frustrating and the devs don't even care to respond to our problems
