5e is my third favorite dnd system.
As for rules. Rules should not be changed willy nilly. Rules matter. Why? Dnd is a game. While story, writing, characters and all that matter; ultimately dnd is a gane and all games need Rules. And, the story should not trump the rules except in very specific very unique situations. Without the rules mattering why play a game. Just read a book or watch a film. The best rules lend themselves to story, choices, and characters. A great story leans into and takes advantage if the rules it doesnt ignore them.
