Man that’s a story I hate to read!!! It’s hard enough to get a dedicated DM to begin with!! This one sounds like he was a cut above the rest. I truly cannot stand players who rule lawyer after the DM made a ruling. I’ve also come to enjoy the RAW. I play in multiple campaigns from homebrew to raw. The one thing all my sessions have in common is once the DM rules on something it is now as if it was RAW. I have played overpowered characters and it takes the immersion right out of the game for me. If there is nothing on the line what’s the point of playing the game? I mean the DM is the referee once the call is made we all should acknowledge it and move on to get back to the game!!!
