WayneLigon said:It does. Every edition of the DMG has had words to that effect.
The people who are going to be asshats never listen to that advice, for some reason. And there have been tons of articles written on how to be a good GM, almost all of them reinterating the same advice. I have not seen an appreciable effect on the GM population.
In that case, you could very well argue that since the people never change, any attempts to impose "balance" from on high aren't going to do much to solve this problem.
The obvious solution, regardless of system, is to find people you're happy playing with. Frankly, I can't imagine gaming long-term with anyone whose play I could tolerate only because he was being held in check by the rules...
