Things DMs do that drive you absolutely batshit insane.
WHY, MAN? WHY IS IT THAT WHEN I ROLL UP A FIGHTER, WE ONLY FIGHT ARCANE SPELLCASTERS? WHEN I ROLL UP A WIZARD, THERE ARE NINETY TARRASQUES, WITH SPELL DEFLECTION AND RESISTANCE COMING OUT OF EVERY ORIFICE? WHEN I HAVE A ROGUE, SHIT, SON, UNDEAD AND CONSTRUCTS AND OOZES! PALADINS FALL, MONKS BECOME CHAOTIC, HUMANS ARE TURNED INTO ELVES, ELVES ARE TURNED INTO DWARVES, JESUS SHOWS UP AND TURNS MY AWAKENED GLASS OF WATER INTO A GLASS OF WINE AND GUESS WHICH DMPC JUST TURNED OUT TO BE AN ALCOHOLIC? THAT'S FUCKING RIGHT, ALL OF THEM DID, AND NOW THEY'RE GOING TO HAVE A BATTLE ROYALE TO SEE WHICH ONE GETS TO FINISH ME FIRST
