I advise finding better players. It solves most of these issues.I wouldn't even say it's a DM vs the Players issue. It's more of an issue with players purposefully asking dumb things they know won't fly, but ask it anyways just in case.
The "rules of yes" is nice and all, but sometimes you do have to say "No, you cannot dual wield great crossbows that are two sizes bigger then normal."
Page reference? I have read the DMG and dont remember anything like this.Also, was the rule of yes the one in the 4e book that had the example of the DM being told what to do? Because that was like the worst argument ever for that rule![]()
If it was there I might well be tempted to applaud it. The idea of the Viking Hatted GM ruling by dictat from his Ivory Tower is one that needs to die.
Yes I am exaggerating for effect and no I am not comparing you to said GM however its pretty obvious that such people do exist.
