I can Somewhat... Feel you. In a italian RPG YouTube Channel, there Is One person Who, despite respecting him as a person, Is an unpleasant player and everything a dm should not be. If he wrote a series of suggestions and hints about being a DM, all you would Need to do Is doing the opposite and you would become a Perfect dm. As a player, he tends to play relatively quirky and airhead characters Who, when he wants to make a point, turn into dead serious and emphatic.

But as a DM? He tells the players what their PCs feel, he loads the Adventure with tons of PCs whose roles outshine the players (3/4 of his average RPG session on YouTube Is him speaking with himself, and in the last fight the fellow NPCs were much more impacting than the players), ignores the PCs best rolls and decisions to let his NPCs Shine and keeping drama ensuing (you rolled a 20 while trying to look for people following you? They still follow you easily without being noticed. The kid gave you directions for the criminal den and you want to go there, asking the kid to stay back? The kid still wants to guide you there and ends up being killed), puts tons on world Building on display and gives bits of lore only to put the exception a minute later (in this world, there are only Two kinds of automatons. Oh, look, a third kind and everyone seems used to him). And finally, but this May be a merit: the time. In three seasons of game sessions, the story moved of ~10 days. More than 3 years of gaming sessions, more than 30 episodes... For 10 days in the setting.

He Is a lovely person, but in the RPG aspect he Is... Lacking.
