This guy breaks down just how bad the layout of the new PHB is. The cross referencing is non-existent and the subsections seem to go in the order someone thought of them. I’m sadly unsurprised that they’ve not improved on any of these problems which existed in the original 5e PHB.
My professional input, knowing nothing of your shop or location, and all respect intended: hosting DMing “lessons” using other systems like PbtA, SwoN, Starforged, Quest, Kids on Brooms/Bikes, etc. to hone narrative improv skills can often set a foundation of non-D&D preferences — especially when the aforementioned are super easy to get started, thus promoting a higher frequency of game sessions for your fledgling Storytellers/GMs. Hell, offering a free/discounted game room rental to the groups these GMs put together could be a great draw (& good optics) 🤓
