Now there's a rule the certainly totally didn't come from a ton of people playing "Chaotic Neutral means I get to be a 'lol so random xD' murder hobo" type characters at all.
Now I'm not really a fan of forcing people to play Good alignment characters, but my god if there was ever someone that wouldn't be allowed to play anything but Lawful/Neutral Good at my table it would be Mr. "I can just be a Good Slave Owner" over there.
