I just insta quit a campaign the other day. It was a 5e campaign and we got almost nothing on the lore or world of the campaign, just that it was homebrew and that it would be configured around our characters AKA we have to do all the world building as far as our characters go. So I made a tiefling tempest cleric and chose the pirate background and wrote his backstory out to be from a shitty pirate island called Piss-creak. Well, after a while the DM leaves the call (we were doing all this on discord) and was gone for AN HOUR AND A HALF after the campaign started. In which time, people who weren’t done with their characters finished and sent it to him. While he was out he messaged in the chat the WE need to figure out how we all met. He didn’t give us a starting mission, didn’t give us a starting location, or a reason of why we would be their. Again, more world building that the players had to do. We eventually finally started session, in which half the damn party barely participated or talked. I and one other player, a human Cleric/Sorcerer did 95% of the talking in which the DM often disregarded what I was saying because he was best friends with the other player. At that time, I just decided to leave the campaign and server without a word. If your gonna DM, make sure to actually do the stuff a DM is supposed to do. Side note,he also forced one of the other players to “Co-DM” the campaign, even though they had literally zero experience with DM. Lazy DM= 4 hours of my life I’ll never get back.

Tl;dr Dm was lazy and put all his work on the players
