You know at least that creator kept it real and straight up said I dont feel like doing this anymore but maybe one day I will. Then gave fans a full story and ended the 2nd part.
I don't know what's going on with Togashi and Miura but they need to get their **** together.
Look at how the wiki for their manga read about the production and release schedule history
"There have been several instances in which Togashi has apologized to readers in Shueisha's Weekly Shōnen Jump for low-quality artwork and promised to redraw portions of the chapters for their tankōbon (collected volume) releases.[22][23][24] In addition, the publication history of the Hunter × Hunter manga has been plagued with hiatuses, in which serialized chapters would be separated by extended periods of time.[25][26][27] After returning from a two-year-long hiatus in June 2014,[28] and joining the English-language Weekly Shonen Jump lineup, the manga went on another just two months later.[29] The series returned from this hiatus, which has been its longest to date, on April 18, 2016,[3 however, just over two months later, Hunter × Hunter began another hiatus on June 4, 2016.[31] It came back on June 26, 2017,[32] and just over two months later, on August 31, the series went on hiatus again, planning to return by the end of that year.[33] The series came back on January 29, 2018,[34] before going on hiatus again on April 9 of the same year.[35] After a five-month hiatus, the manga returned from September 22 to November 26, 2018, before entering another."
"Berserk is known for its frequent and often extended hiatuses,[7] which date back to late 2006.[8] After a 10-month hiatus from September 2014, the manga came back in July 2015,[9] and until December 2015, it was published monthly before returning to an irregular schedule.[1 It was published monthly from June to September 2016, before entering another hiatus.[11][12] The manga resumed from March to June 2017,[13][14] and then from December 2017,[15] it was published on a regular basis until May 2018, and nearly three months after, a new chapter was published in August before entering an 8-month hiatus.[16][17] Two new chapters were published in April and August 2019.[18][19]"
It seems to me they log in like 200+ chapters to get popularity then option the ip for anime, merch, movies, live adaption, etc. and then they just sit back and collect the royalties.
Otherwise there's no way these guys could make a living releasing issues at the pace they do
