I really hate whenever I try to explain how some bad rules can be abused and immediatelly get someone say shit like "If this happens in your group, change it" as if that would solve the problem. And whenever it is not soemthing you witnessed personally, then it means it never happens and could never happen.
There's a thing in D&D forum spaces called the Oberoni Fallacy. The fallacy goes that, if someone says there's a problem with a D&D rule, they're wrong because they can just Rule 0 it away. It's a fallacy because they have just proposed a solution to what apparently isn't a problem.
People constantly saying "the rules are just guidelines" to any D&D problem is the same sort of idea. Yeah, I know you can ignore them, but I paid for the damn book, so I want what's IN the book to actually matter.
