I can't speak for anyone else's abilities but mine. I know that it is at least EASIER to GM such a game when I have a system which simply puts that stuff on the table. I could try to run a 5e game like a DW game, sure, but I'd constantly have to be trying to figure out what to do next to get it to work. 5e doesn't have an equivalent of 'success with complication' either, which is one thing that is pretty commonly used in these games. I guess if I am, again, a very sure hand at this technique I can adjudicate just the right amount of those into play, but DW just tells me when to do that itself. It also allows bonuses (hold etc) that let players mitigate that possibility somewhat. I guess I could add a 'coupon' to 5e that did that, but then what would I tie it to? Now I'm adding mechanics.Sure. I guess I just think it's possible to DM 5E (because that's the version I know best at the moment) to be approximately as player-responsive in extent, if differently in kind as DW (because they really do work differently).
Why did the party choose to fight the mythic death knight in something an awful lot like a cage match?
Frankly, while I have written pretty much a complete RPG, there are other people who are probably much better at it, and its a lot less time-consuming to read their material and use it. If I'm already adhering to basically a DW agenda and principles, why use 5e rules?
