If you set up a strawman, you're not exactly proving anything by knocking it down, are ya?
The "straw man" in this case is a representation of the flaws in your analogy in
this post. If it is a straw man, then that means your own argument is invalid for using that straw man to try to prove your own point.
Consider that at some tables, rewriting the mechanics doesn't require any of those things. They're all superfluous. Hey, I just plugged two new ability scores and a half-dozen DMs Guild class options into my new game, who cares how balanced they are? I'm the DM, I make the judgement calls, as long as we're all having fun who gives a toss whether you kill the necromancer in five hits or in seven? Hell, maybe I don't even track HP, I just declare something dead when it seems like people are getting bored of fighting it. Attack rolls? Never figured they were necessary, my group just rolls damage. Game works like a dream.
And those tables are playing with their own homebrew systems and likely never use any further products, thus would not be subject to issues of errata making a character design suddenly useless. Making your entire stance pointless.
At this point, you are arguing against yourself.
Consider that at other tables, "Drow are actually jungle elves who are nocturnal" is met with, oh I don't, now, someone saying, "Well, they're not really Drow then, are they? I mean, maybe they're fun and all, but they're not what anyone would call Drow. That's just not what Drow are. Never have been."
People tried the same argument with how Eberron presented Drow. End of the day, setting is setting; if you don't like it, you don't have to play that setting.
What you're illustrating here is that you personally care more about mechanics than about story. That's fair enough. Even expected on a site like ENWorld. But that's also not the way everyone plays the game.
You think I don't care about story? I said I wasn't concerned about
canon in my first post on this thread. And I also made it clear that any changes made for story purposes
don't affect canon.
My comment about players wanting to know more about nocturnal jungle drow was to illustrate that you've hooked them into the story at that point with your entirely new lore. Because at that point, you have their interest, and you can tell a lot more drow-oriented stories that serve to feed their hunger for this new lore. It's not simply an adventure or roleplaying hook, but a way to draw them further into the world and open the door for more campaigns in the future. Maybe your next campaign is entirely drow-centered, so they learn massively more about the setting. Maybe it's exploring a culture that is an enemy of the drow and getting a more nuanced viewpoint of how they interact with the world. Maybe players even incorporate that new version of the drow into their characters and have it be somewhat central to the individual stories of those characters.
Changing lore/canon is very much related to caring about stories. It's related to "how can I tell a good story, and what do I need to change to make the players interested?" Most players I have are not interested in Drizz't, so it doesn't hurt the FR stories I tell to simply replace him with someone else. Someone written more to their liking.
And it makes it
my story and not me simply retelling someone else's work.
I'm sorry that you do not see how it is that people can manage to not care about changing canon and care about story. You don't need to be a parrot to care about story.
