Edit: wanted to edit this one more time to say you really need to increase the rate of stamina recovery. It's abysmally slow, as if you don't want people playing your game.
Whose brilliant idea was it to add a third currency to the game? It's as excessive as splitting your rare and normal gachas. Your gacha just plain sucks. Doing a multi for a bunch of useless fragments, not even full characters, will immediately drive people from this game. All you did was add a bunch of flashy animations to things inconsequential to the actual game. That's all you're getting from me because I'm not wasting me time just to have the data deleted again.
