They keep taking down negative reviews. I'm not "rEvIeW bOmBiNg" I'm just giving my honest opinion, which happens to be rather negative. You run out of free ways to get premium gems way too quickly. Story mode is way too short. Arena is already dominated by whales as they all have a full team of URs. Drop rate for URs is way too low. You can't really do USJ unless you have a lot of characters, which is hard to do when they barely give you any gems. Basically it's a typical gacha game.
