This isn't really a novel idea, but more of a little list of things that I think make novels better or worse.
Whenever I read a novel there are somethings that make me look out for a novel and look forward to it:
* Release schedule or scheduled release rate (such as 4/week)
* A synopsis that actually tells about what to look forward to in the novel, instead of just telling about the world that the novel is in
What I think degrades a novel:
* Using words in a different language that isn't meant in a joking isn't really enough to make me drop a novel, but it does annoy when people use random Japanese words without explaining their meaning
* When the MC is just forced into a situation because the people around him don't understand the basics of what they should considering their positions (like a genius that the lord of city hunts down for bumping into someone in his family. It's just too forceful to be good but also doesn't make sense for a person who governs a city to do something like that since it has no benefits from him and many risks)
* When the MC is too easy to kill, sometimes it is alright but for other's it is just ridiculous. Like they will make the MC kill his lover just cause she said something that would annoy the MC or that it will cause many troubles for the MC in the future.
* When the MC is too hesitant to kill, even though it could save him potential troubles and just be smart on his part. Like he gets a treasured herb and some rich kid comes over demanding he hand it over and the MC says no and they start fighting and he beats up the kid instead of killing him like he did the guard and the rich kid goes and tells his parents or master or whatever about it and now the enemy has offended the emperor or an entire sect or whatever
* When the harem becomes too much. A perfect example of this is Martial God Asura for me. It used to be my favorite novel, ruthless MC that always pays back his debts in full, cool fight scenes, and pretty good world building, but now it's barely good enough to make it in my top 30 cause of all the harem. The MC would literally get together with every girl he sees, like they could be fighting less that 3 chapters ago and now he offends the strongest sect in the area for a girl, even after the girl says she will kill him even after he saves her.
*When the author goes into tons of detail about the MC's lust and describes every single girl the MC looks at with perfect curves, large breast, plump perfect thighs, and stuff like that. It's okay in small amounts with a few characters but there is no need to go overboard with similar descriptions of every girl the MC meets. This one honestly isn't a big deal at all, as there is only one novel that does it enough to annoy me.
* When the author uses the word 'pussy' or 'pussy flaps'. I personally cannot stand this one it bothers me a lot because there is no reason to point out stuff like that. This is the reason I dropped "Fairy Tail System in Fairy Tail". I know it might be overreacting or whatever but I really can't stand this because it makes a bad impression of the novel in that it seems to be needlessly dirty with language like that. Just the overuse of "Adult Language" in general is annoying because it makes the Author and the MC seem stupid with a limited vocabulary. The occasional curse words are fine but if you make the MC curse every sentence, multiple times a sentence and repeat the same curse words then it does not look or sound good at all.
* When the MC tries too hard to hide his own abilities, even though it isn't really needed and is just the author trying to make the MC underestimated and humiliated as a chance for him to retaliate against the ones that do that to him, who just so happen to have a strong background, and will make him go through unnecessary troubles just for him to get stronger with no actual purpose behind it.
I think the best thing here is just the simple scheduled release rate and the worst thing is the harem cause the other bad things are forced for the MC to grow but the harem has no reason for it, because it doesn't benefit the MC in any way and just causes the needless troubles for him and is a headache for people like me to read it.
