Big corpo stuff I guess. If it's not making any (potential) money, then no publishing either. Adrenaline, gratification, or whatever that keeps on people coming back. Put with alpha gen terms it'd be "hype moments and aura" type of pace. Tho they can't fully do that like manhwa coughSolo Levelingcough so it still needs an actual story here and there.
See this is what I don't get with Mangajump. You'd think the majority of the users love fast paced story but there's World Trigger with its slow-but-technical pace that managed to go up to 200+ chaps. and a good chunk of readers too. So why is it that one's slow paced manga is loved while the others disliked?
