That is terribly unfair and quite simplified.
First you tell a fellow DM that he is stubborn if he does not include an optional rule. Second you imply that it is inherintly better to use the optional rule, because you think you speak for everyone else. Third, the desire to have meaningful choices that are more than just: my character is only 4ft tall and calls himself dwarf, but actually has all the powers of an elf also needs to be taken seriously.
For the first two points, if that's what you took from what I've said, then either I was not clear or you misunderstood.
To make my point clearer hopefully... I have no issue and do not think a person is in any way stubborn for not using an optional rule. In point of fact, I think everybody SHOULD make their own individual choices on whether or not to incorporate those optional rules. That's the point of
having optional rules... so you can choose to use them or not use them.
However, if you don't like an optional rule... you don't get to demand that WotC NOT PUBLISH said rule in one their books. That's the point and has always been the point. Even if you think it ruins the game... the rule can be published, probably will be published, and then you have to make the CHOICE not to use it.
Now that being said... one of the "reasons" some people were giving as to why the optional rules should not be published at all is because if they were... then their players would expect to be able to use them. Understandable... BUT NOT WOTC'S PROBLEM. That is YOUR issue as a DM. If you have rules you don't want to use and you have players that do... then YOU have to choose what is more important... your choices, or your players.
Quite frankly... I don't care either way. If you inferred from my posts that I would side on the players on this choice and that a DM should acquiesce to their demands and allow the rules they don't like to be used... in truth it's the exact opposite! I am
entirely for DMs picking and choosing which rules they wish to use for whatever game they are running... whether than be any of the "optional" books like Tasha's and Xanathar's...
and even rules within the Player's Handbook. You want to run a game composed entirely of dragonborn? Go for it! And if a player comes to you asking to play a gnome, then you are more than within your right to say "No. Dragonborn only for this game."
But apparently some of the people in this thread have a hard time making that decree. So rather than THEY make the decree of "No, you cannot use the Tasha's rule of placing your ability scores wherever you want"... they want WotC to a NOT PUBLISH that optional rule so that they don't have to.
And I will reiterate again that that is a
ridiculous reason to give for why WotC should or shouldn't include a rule in the game. And thank goodness WotC has the good sense to not listen to that kind of reasoning.
And finally... as far as your third point is concerned... you and I will just have to disagree on what is an actual "meaningful choice". Because I don't think keeping a demi-human's ability score bonus to only what is printed in the Player's Handbook is in any way, shape, or form...
meaningful. Why? Because rather than a Dwarf from the PHB starting a new game using Point Buy to get an INT of
15 (
which they can have)... Tasha's now will allow them to start with a
17 instead. A single, one point difference in modifier.
Like I said... not
meaningful in way, shape or form. A point better? Sure. But not meaningful. And I don't believe WotC needs to worry about that... and by all accounts, WotC doesn't.
