Has potential but is just too greedy. Gacha only gives fragments (aka gotta roll a lot of times before you unlock a new character), also has gear gacha. Adding to that is how expensive rolls are: 1 roll = 500 rubies (premium currency) 10 rolls =4500 but outside events you get less than 100 rubies from dailies. Rubies - RL money conversion rate is horrible as well. Game also has a tendency to slowly stop working forcing you to restart the game.
