Glytch

Mine was a minotaur gladiator turned monster hunter (ua fighter subclass). His name was Daniel Notmonster and he'd been called monster so much during his days in the arena that he internalized a hatred of monstrosities. He was driven to prove he wasn't a monster by killing any he came across. He would also collect a bone from each monstrosity killed to scrimshaw a scene of the battle to kill it.

This is why you make friends with an artificer.

Alaka-BLAM!

It's an improvised melee weapon when you smack someone with it because you aren't using the weapon as designed.

No they don't, they just add a greater number of misinterpretable rules.

I'd say you're wrong there too. It's about the players and DM collaborating, improvising, and creating the adventure we all want to have. We're all in this to have fun and tell interesting stories. It works best when everyone is bought-in and affecting the story.
