Blatant powercreep, HP bloat, shitter instead of a story etc
Quite often gachas start off with bad stories but get better over time, HSR is the opposite, it had a great start, a cool boss, nice events and then proceeded to get worse and worse. Nonchina that sucked giant dicks, nonbroadway that looked promising but didn't deliver at all, nongreece that's boring as fuck. I kind of lost hope.
