FireLance said:There seems to be some unstated assumption that a DM must have the right to change the rules or he is not really a DM. Why should that be the case?
Well, rule 0, but I think it goes beyond what is allowed to the DM in any of the books.
The reason is because, at the base of it all, the DM is telling a story that is his. If a rule doesn't fit within his idea of this story, or he thinks that it will add to the enjoyment of the game, it should be his right to change this rule. It's a player's right to be notified of this. If the palyers state that this is going to lessen the enjoyment of the game, then consider not making the change.
In the game I played before I started being the DM, I was one of the primary culprits in enabling the fighter/rogue to obliterate enemies with sneak attack damage, allowing her to dish out 10 dice (plus bonuses) every round at will. I considered her a tactical walking fireball. In my game, I wanted a sneak attack to be more of a focused effort, so I changed sneak attack to a standard action. To me, the sneak attack rules were abusive, and didn't fit with the style of the game I wanted to run. So far, in the year that we have been playing, the new rule has not taken away from the game or the enjoyment, and the new rogue works hard to use it as often as possible.
