It's... fairly obvious that the Myth girls are burning out.
Calli has always been an infrequent streamer due to her music making.
Ina took her month long break because she flat out stated she was burnt out and due to streaming so often she's forgotten her purpose, her reason, and her drive for joining Hololive and wanted to spend some time thinking on that.
Ame is the most creative of the bunch, which meant bad news for her because you can't be creative forever. You have to settle into a rhythm eventually and she never did. She went from 2nd behind Gura, to last place in views and CCVs because she kept bouncing from creative idea to creative idea and eventually burned out when she ran out of ideas and stopped streaming often.
While Gura hasn't overtly stated anything I am aware of, she's spilled her entire life already, openly hates white names, and has just slowed down streaming in general. All signs of the honeymoon phase being over for her and she's struggling to find a reason.
The JP girls treat this as a job, so they can hunker down and pump shit out. The EN girls see it as a hobby, and we all grow out of our hobbies eventually.
