My Dungeon Master has made his own story and he asked how it was. I criticized him about his story only being interesting for one character (that has a massive amount of backstory and was made with the DM). I complained about it not being interesting for the other parties. Right now for the story guy, his turn lasts 30 to 45 minutes (I timed it) while the rest of us get cut off at after 5 to 10 minutes.
His response was to rage at me for “having a shitty character” and getting on his nerves.
He also rewards for kinda being a slave to his story. When I try to branch out from his story I get cut of almost immediately, or says I have a small chance to do something and he cuts me off from doing it when I roll low.
(This is just how I see it though; he seems to think he is almost perfect.)
I'm new to D&D so I don't really know how this is supposed to work. Is it the Dungeon Master's job to keep the story interesting for other players, or is it the player's task to write a massive backstory to fit in?
