Who said they were useless? I find them a useful starting point. They're just not the end-all. And, for the record. I think you are just as special, as is any competent DM (I assume the average ENWorlder is a competent DM). Every DM has a style and knows his players, and uses the rules to create a game that reflects his style and engages his players. D&D is an open-ended roleplaying game. It's not chess, Warhammer, or WoW. There are no winners and losers, and everything is open to interpretation. Most designers understand that. And embrace it.
If I were one of the game designers you refer to, I would have absolutely no problem ignoring any of your concerns about my game as a result of what you just said. It's one of the most bafflingly condescending things I've ever read.
I doubt the actual game designers would agree. It's not condescending to suggest that you use houserules or that the DM interprets the rules as he pleases. Do you think Lipton gets mad if you buy a packaged rice and beans mix and add some peppers to it you got from the farmer's market? The rules are intended to be used to create a game. It's not the designers' job to play the game for you, and
they would be quite pretentious to think otherwise.
