I wouldn’t exactly call reading this for more than 10 years impatient. But if I disregard your personal attack -for the story to remain consistent, certain plot points should be resolved within a reasonable amount of time. Are you referring to Yana’s age (42) when you say there’s plenty of time to resolve all the clues?
I would agree with OP, cause personally I would not say that the story has improved, in fact I think it is evident that Yana has given priority to other projects. So short chapters and secondary stories taking more than half a year to finish seem exaggerated and decadent to me. I was 18 years old when the story of OC was confirmed - it's been almost 10 years and I thought it was the pinnacle of the story, the climax, but I don't see where it's going to take everything that is being triggered now, and most of all the time it will take us to get there with these short chapters.
Yeah I agree. The person saying we need to wait to get better quality is high of copium —_—. Anyway yeah it's very clear Yana is prioritizing her other projects. Particularly Twisted Wonderland seems to be their main focus. In general I think it's hard for the serie to come back again in terms of mainstream-ness
The recent anime for Black Butler was ok but, genuinely I heard very little noise from viewers and even a hardcore fan friend of mine didn't watch it since they chose to drop the serie due to really poor pacing of uploads.
They be dropping plotwist or mystery element in one chapter but, then disappear for months and years to get back to it.

The whole story is starting to feel off. Partly because of how slow the updates are, but also because so many clues and unresolved plot points have been left hanging throughout the arcs. It feels like the author themselves forgot about the main plot and just started focusing on side stories and introducing new characters.
I’ve even tried rereading the whole story a few times, but I still feel the same way. At this point, I think I’ll have to wait until the manga is completely finished and then read it all in one go, because I’m just not interested anymore. It’s honestly sad to see such a good story feel like it’s going off the rails.
