No, they certainly are not. And it's totally impossible to make an adventure that caters to every individual. That doesn't make the module broken.
Sorry, but this is broken. A monster that the PCs are encouraged to fight that has the chance to kill some or all of them in round one is broken.
Just because something is written down does not make it a good idea. Just because something is in an official WotC module doesn't mean that people should be lemmings and believe "yup, yup, that's a good idea". Having this dragon in the module was a terrible idea on their point. Your idea is a lot better than their idea (but still not good).
Maybe the people you play with are like that. The people I play with are universally lovely and open to imaginative solutions.
The vast majority have never been like that. But then again, people are people. I have no idea about Nemio's players, but he did say that he was a new DM, so I wouldn't suggest anything that might tick his players off or might alienate them from the game. Or even might teach them that the way to fix a PC death or a TPK is to reset the clock.
Sure is. And I like my fun better than your fun.
As you should.
I could go on about how your ideas are lousy, but that seems pointless. I'm really not interested in your opinion. I've read a bunch of your posts today, and it turns out that I disagree with you on pretty much everything. My suggestions were for [MENTION=6775814]Nemio[/MENTION] (who asked for suggestions), and he/she can take or leave them.
I did not say that your post was lousy. I said that one idea was lousy. I posted to let Nemio know that he shouldn't listen to your advice on this one idea.
New DMs shouldn't have to walk a tightrope of making sure their players do a few set things right, or we reset the adventure.
That's just bad advice to a new DM. It's something he might experiment with later on when he is comfortable, but it's not something he should try out of the box. YMMV.
