I wouldn't care if all the Sugu/Sinon/Alice* content got cut down going forward, because their stories have never had anything to do with the Kirito, Asuna and Inoda plot. If you remember in part 1, they were just there to add scenes. Like when Charlie shows you videos, or there were posts on the perv forum, or the video shop in FoG. The focus of the game was still 90% Kirito's day-to-day, going betwen school and FoG with Asuna, with Inoda taking his opportunities with Asuna wherever he could get them.
* Notice I didn't put Liz in there? Because she is at least directly tied to the main plot, albeit in a secondary way as Inoda's co-conspirator. But I'll be honest, I don't like Liz' bdsm sadist content or the direction it might be going. But Sugu who, until the last update where she lewded Kirito, was just there for Kirito to talk to at the bar between scenes with Hebishima. Basically, I want to see the side characters being used in the main plot, or not at all. I can see the Alice sub-plot we got so far all being an excuse for Kirito to get to the house next to the brothel, which could make for some great NTR moments in the future. If that's what it was for, that's okay. But it probably should have been a shorter event, exactly when there was something to see.
I think another problem might be that Fujino believes 'Sister-NTR' is just as good as real NTR, so to Fujino all the content about Sugu is 'on theme' and not just a distraction.
