Its ironic how most of the worst aspects of part 2 are resulted from the questionary organized by Fujino at the beginning of part 2.
In a way, the supporters and general audience of Fujino cucked themselves while hoping to get a more slow burn emotional NTR story, but receiving a half-baked unfocused NTR cliché filled story.
Alice came to be thanks to her being voted/chosen in the questionary. Alice story could have been easily given to NPCs or just be a quest in FOG, and Alice screen time repurposed to better secondary stories.
Hebishima was removed from the story thanks to the voice of the Fujino audience shared in the questionary. Hebishima was a stereotypical NTR protagonist, but at least his role and actions in the story were consistent in part 1 and some of part 2 before it was softly removed and then gender bent.
The council existence in the current form, most likely, exist because of Alice inclusion in the story and the decision to remove Hebishima from the story. Without Hebishima there was no source of secondary NTR events.
Sugu and Sinon plot merge resulted again from Hebishima removal and people choosing in the questionary to have Kirito be able to have sex with other girls. It would have been better for Sugu and Sinon story to be kept separate or at least joined as Fujino originally intended. And Kiritio could still be getting scenes with Sugu and Sinon, but this time they would have been conditioned by Hebishima as a way to demonstrate his dominance and corruption of Sugu and Sinon to an unknowing Kirito.
Kyoko and Liz underuse in the story is due to the choice of going too far with the slow burn and for Fujino inexperience with this type of setup for a NTR story. If Fujino had kept to his usual pacing for the story and just moved focus to other character when he needed to slow down and shift focus, then we would have had more diverse events and more unpredictable story telling.
As things are now, we are basically waiting for each update cycle to recycle ideas and content from part 1 and other Fujino games but with the extra addition of having several events to get what in the past was done with just a longer scene or a buildup made from exploring the map and a payoff from witnessing another perspective for the scene.
I think the only thing that's unanimously agreed upon as the only bad addition is just Alice.
The council plot line is kind of dumb, but thinking it's because Hebishima was removed is probably incorrect. But anyways in regards to Hebishima being removed and giving Kirito time with other girls, I think those have been relatively well received by a decent chunk of people. It's also been received poorly by others, but it's not something that everyone generally agrees to being bad. Anyways in regards to the council plot line being the result of losing Hebishima, the Administrator character was available from the beginning of Part 2 before the poll was posted.
It's more than likely that Fujino wanted to gauge interest on if the new idea (Admin inclusion and Hebishima removal) they were working on would be decently well received. But the point is that it's something that is entirely on Fujino who wanted to focus on the direction Part 2 went other than forcing Alice into the plot. Liz for example didn't need to be here, but no one had any influence to bring her in, instead it's just Fujino wanting to bring more SAO characters into the story and kicking out all the side npc characters from Part 1.
I do agree that certain characters are underused and the focus is a little whack, but this more than likely has to do with the way Fujino works more than anything else to be honest. It would overall be better if Fujino had less characters and plot lines to work with, considering the method in which they develop this game is on a monthly basis. It's similar to a 40 - 50 page manga chapter per month, and there's only so much content you can do in that time span. Fujino in their efforts to return people's investment on CI-EN/Patreon leads them to release once a month and generally focus mainly on Asuna, which throws a lot of other characters and work onto the side. Basically they needed to have either less characters or work on a bi-monthly schedule (or longer), to allow them legitimate time to develop things.
In regards to the cucks you might mention question, I would probably say it's anyone paying and complaining to be honest lol. I'm personally ok with things, but I'm able to analyze and recognize what may or may not be wrong with things going on. But gotta also chill and be like "it is what it is". I appreciate the amount of work and effort they do so I just kind of go with the flow with it and not get too uppity about it.
