RE: Asking for information, and being dissatisfied with the response.
I'd like to enter in the form of an anecdote. I've been playing D&D for 3-4 years now. I picked it up as a side hobby in high school, and convinced some folks to play with me. I even wound up DMing after a year of watching on of my seniors work the screen. When he graduated, it sorta fell to me. Even DMing for 3ish years, I've made plenty of bonehead mistakes. I thought the best way to make challenging encounters was to just pick a single higher-CR monster. I allowed a PC to be a minotaur, Forgoing the 7 racial hit dice, and thinking that compensated for letting him start as that race at such a low level. I had no problem with PC's murdering each other. I figured a were-bear cleric PC would somehow work itself out, and prove to be fruitful. I thought Magic Item costs just went up 1,000 GP per magic item level. I thought blaster wizards were the greatest thing since the Playstation 2. And with each of those screwups, something has visibly gone wrong. The level 3 minotaur stomped over everything. The were-bear spent most of the campaign trying not to shift to bear form. The party super-sized their equipment and turned every encounter into a trifle. The single, big huge monster either fell with little more than a thought, or annihilated the party.
I'd watched someone DM for a year, but when the job fell to me, I was still clueless. Worse still, I didn't know I was screwing up the things I did. The only way I did so, and the only way I've gotten better as a DM is to do it. My mistakes either showed me the correct solution, or prompted me to research, and find out what was wrong.
...And that's what this rambling story is about. You and I both surely have a fair bit we still don't know about Gameology. However, there comes a point where it's not feasible to look off the other kids in class, and instead to go try stuff on your own. By far, the most effective form of learning is by screwing up. In the immortal words of a Magic School Bus driver, "Take chances, make mistakes, get messy." We'll get more out of gaming if we don't focus on arguing points or belaboring others for information, and focus on trying things for ourselves.
I hope this story was insightful, or at least entertaining. I'll head back to lurking, now.
