Fanfic It's a bad story... which is sort of an achievement.
Forged Destiny is a bad story, but not a bad fanfic in a usual sense. Let me elaborate.
When a fanfiction is called bad, it means that it is absolutely horrible by the standards of any other media. It means that the story is full of errors, unfinished, immature or several of the above. It means that only people looking for a specific thing, like their favorite pairing or an unusual story concept, would find it worth their time.
Forged Destiny has none of the above-mentioned problems. It contains almost no grammar or spelling errors, the author doesn't show obvious hatred nor favoritism towards any character and it actually looks like a fairly good adventure story for the first two arcs. But the Romantic Plot Tumor, flat characters, annoying characters, informed flaws, inconsistent themes, unsatisfying conclusions and numerous contradictions soon begin to pile up, resulting in a story that is not only unengaging but downright frustrating at times.
The author is clearly talented and puts a lot of effort into his works. A story of that lenght and writing quality could be published as a novel, or even a series of novels. But they would be mediocre novels at best. And with all the characters being vastly different from their original counterparts, there is little reason for RWBY fans to find it particularly endearing. At the end of the day, I would recommend doing something else with your time than reading it.
Fanfic Started out good but became an inconsistent mess (Spoilers)
Forged Destiny started out great. It combined story ideas I love; i.e. taking established characters and placing them in a world that runs on RPG Mechanics, and giving the main character (Jaune) a dream that forces him to go against what society demands of him. I love stories where the protagonist has to fight hard for their dream because society says they can't achieve it because of something they're born with. The plot was interesting, the fights were enjoyable, and the characters were fun, if a little one-dimensional at times.
Then the Romantic Plot Tumor crept in. And Informed Wrongness. And retcons, Plot Holes, unsympathetic protagonists, and inconsistent writing galore. Add in some plot-induced drama and stupidity as well. Not to mention how little details like characters' ages from previously-discussed events were changed because the author apparently forgot said details.
My biggest gripe is probably when Jaune became a member of the Hero class, destroying the initial message of the fic. Jaune no longer had to go against society's demands to become a Hero since he is now a Hero. He does not need to rebel against an unfair system to achieve his dream. Well then. Bye bye, former message that being Labor Caste does not mean you can't be a Hero. In order to be a Hero and not get into trouble, you have to change your class!
If I had to sum this story up in a word, I would call it "disappointing". The only reason I still read the fic is because I have already put hours into it and I may as well see how it ends. (Update: I've now dropped it.) Disagree if you want, but I recommend Coeur's other fics (such as Professor Arc and Relic of the Future) over this one. They're more consistent.
