In video game design there is the MDA framework. Where mechanics (rules) create dynamics (gameplay flow) that express aesthetics (genre and emotional expression). Thus in d&d the rules change the actions players take and these actions determine the tone and feel of the game. This is why Silvery Barbs is miserable, the dynamic it creates diminishes the roleplaying aesthetic by breaking suspension of disbelief.

When looking at 5e the fact most players don't just homebrew a few rules, but gut large mechanics (light, encumbrance, gold, travel) of the game. This has completed removed WotC's control of D&D's dynamics. This breaks the aesthetics of the system. 5e in it's current state is not a heroic fantasy game, but everyone thinks it is. Which is why so many tables fail and new DMs burn out.
