Exploring my own vision of Xianxia Smut with the debut novel, "Immortal Only Accepts Female Disciples"
My pet peeves:
1) I don't think harems should grow too large, too fast. At that point, individuality is lost in the avalanche of free vagina, resulting in flat, emotionless, and boring female characters. New harem members also should not supersede the previous harem members and make them useless.
2) Dialogue that goes no where and only serves to pad word count.
Yes.. Once the harem goes past a certain point, older members tend to be ignored as far as dialogue, plot, and sex scenes go. A constantly skirt-chasing MC is fun to read about, but once I stop reading, I FEEL EMPTY. The story just isn't as emotionally satisfying depending on how much older characters are ignored.
