I mean, you can watch streamed games run by Perkins, Crawford, Mearls, etc. It's not really that hard to find.In the olden days, it often used to be "play the game as designed to learn how it actually works, and then later add your own tweaks to improve the aspects that you feel aren't working for you as written."
A big issue I have with 5th edition is that I really don't know how the rules as written are supposed to be used. There are many mechanics that explain how they work, but there is a lack of understanding on my side of what they are meant to accomplish. What is the 30-minute-gameplay loop of D&D 5th edition that the designers designed the mechanics for? What did they think a D&D adventure looks like in play?
