it's kinda fun at first but it gets boring, grindy and repetitive fast. i don't like how playing most characters is locked behind gacha. almost impossible to get your favorite 5* charas as free to play unless you start saving a year in advance. and even though they should be easier to get, I still haven't been able to get my favorite 4* charas either. and when you get to a certain world level, everything just feels like it takes way too long to kill, even if you do the boring artifact grinding.
