Exactly. It's sort of an uncomfortable middle ground, but also just kind of messy.
And I'm tired, as someone who DMed it a bunch, hearing people act like broken or missing rules aren't a problem, or somehow even a good thing, because the DM can just make something up. Yeah, not shit. I can do that in literally any game I run. It's just unpleasant to do in 5e, yet I have to do it all the damn time to keep the game running smoothly. I'd rather have a game that either supports me as a GM, or is easier to improvise.
