I'm thinking about writing a Fimfiction, but first I'd like to discuss things we love and HATE to see in Fimfictions, this can range from characters to plot. I'll get the ball rolling:
I hate when people make stories where the main character hooks up with one of the mane 6, one of the princesses, or even one of the famous background ponies (like Lyra, Derpy, Applejack, Dr.Whooves, etc)
