]is dead on target. I'm not reading the Monster Manual for enjoyment. I'm reading it because I need a critter to eat my PC's. I don't know about anyone else, but, I generally start writing the adventure first, and then populate that adventure with critters. "Hey, there's a hole over here, let's chuck an Otyugh in here. Oh, wizard's storage room, what kind of weird goodies can I have crawl out of that box?
I've never gone the other way - "Hrm, this bit of backstory about this monster is really interesting, let's write an entire adventure around this". I've certainly taken novels and short stories that I've read and turned them into adventures. But, the Monster Manual has almost never led to anything in play.
I often read D&D RPG supplements for entertainment and ideas, and yes, I've taken lore about a monster and turned that into an adventure. Why not? It's a blast and gives you a good seed to create around. Just because you don't do that, doesn't mean that others don't and WotC needs to give something to all significant groups of people that play their game. Given that it's much easier to ignore than to create, I doubt that they will appease you and screw over the crowd that uses, or even needs the lore to help them create.
Sure they do. That doesn't keep the above from being true for people who like to read.Do people just not read very much?
