I absolutely pay attention to pacing when I run 5e. I don't care about pacing at all when I run Blades in the Dark.I pay attention to pacing a lot, but pacing definitely is a part of presentation.
I absolutely think it's my job as GM to manage pacing in 5e. I don't care about pacing at all when I run Blades in the Dark.
I absolutely use Force and Illusionism to manage pacing in 5e. I don't care about pacing at all when I run Blades in the Dark.
Pacing is function of the kind of game you're running. It is not universal. Other games operate in ways that pacing is just not a concern. So, yes, if you're just used to running D&D, then you're very used to paying attention to pacing. Even here, though, there's differences of opinion about if it's a thing. If I'm not mistaken, @Lanefan doesn't care about pacing either -- this is a feature, not a bug, of his approach to play.
