Why would you want to use 5e for narrativist play? It is really, really the wrong system for that.It’s mostly an academic understanding. I’ve read some rules systems that I’m given to understand are narrativist, and I think they would be fun to play, in a different way than D&D 5e is fun to play, but haven’t had occasion to do so. I have played a lot of D&D 4e, which is generally praised for supporting narrativist play pretty well, and loved it. But, in terms of what would need to change in 5e to support narrativist play? I mean, the basic gameplay structure isn’t really set up for it. You’d need to re-structure the conversation of the game around dramatic conflict rather than environmental interaction. 4e did this by building everything around the encounter as the nexus of the gameplay, and provided a structure for non-combat encounters that was focused on consequence resolution rather than task resolution. You could incorporate some of these ideas into 5e, but I think the result would just be a bad imitation of 4e. And, honestly, there are other, better systems out there for narrativist play anyway.
Where I think the bigger issue is, is when people try making these claims about simulation and how 5e is all about simulation. It's not. It's High Concept Simulationist - it leans very heavily on genre and making sure that play will focus on genre, but, simulation (the plain English meaning of a system that helps to conceptualize how something happens) it is not.
