I don't really mind the premium chapters thing, I also don't mind buying spirit stones "IF" the novel that will be made premium would increase its chapter release and make the quality of translation better.
The thing that I don't like with the current system is that they seem to rush implementing someform of paywall.
I don't want to offend but, instead of having just a handful of selection where i can spend SSs, I would be more interested to buy spirit stones if there will be more selection of good novels that I can spend my SS on.
I am also not a fan of making the previous "supposed to be" free chapters , go premium. It would have been nicer if they just increase the release rate and the extra added chapters would go premium. The current state of free chapters on premium novels is now 1/day that was previously something like 2-3/day.
I think they could have had solved the problem of earning money if they just increased the ads, i wouldn't mind seeing 10 ad posters in a single chapter on free chapters that they are releasing. This way, they could have made more money on regular readers, and slowly implement the premium novels afterwards when they have around 100 nice novels with good quality that i can choose to use my SS on.
