Sure, but that results in a badly designed game. And in games like 5E, where it's a big tent that everyone wants to work in a dozen different ways, the result is a game that can't do any of the dozen things it's "designed to do" well. So focus the design. Make a better game that serves one of those goals well. Make a different game, or even a branch of the same game, that serves a different one of those goals well. A well-designed game with a tight focus is going to be more fun than one that's trying to be all things to all gamers while doing it all badly.
If this is your real underlying premise for your question... then I wholeheartedly disagree with you.
I find zero value in D&D choosing
one direction to go in and making it the absolute best in that one direction, rather than going partway in a dozen different directions so that it can be "all things for all people". Because that basically is singling out one style and type of D&D player and saying "
You are the right one. Everyone else is wrong."
Why does D&D need to "pick a lane" and just focus on that? Those that want it that way... I presume... want it because they wish to say they play the legacy game system that is Dungeons & Dragons, but play it exactly the way
they want to. And anyone else who wishes to be a part of the sandbox of 'Dungeons & Dragons players' has to conform to that direction.
That is an attitude that does not need to be in Dungeons & Dragons.
If anyone wants to play roleplaying games in a particular style, a particular format, a particular genre, a particular focus... there are games out there for them. Hundreds, if not thousands, of roleplaying games exist to scratch whatever itch a particular player or table of players might have-- all of them designed and built to go in that one specific direction full-speed ahead. If you want it... it's out there for you to find.
But it's not Dungeons & Dragons. And at some point you have to accept that it's not and it will never be. That's never going to be what Dungeons & Dragons is. D&D
IS "the big tent". It is all games to all people... even if it's not the best game for any individual person. But there is absolutely no reason why it needs to be. And if someone doesn't like that D&D isn't the best game for what they want... they can just choose not to play it.
But that would require the person to admit they are "no longer a Dungeons & Dragons player". And many of them can't accept that. The idea of being a D&D player is more important than playing a specific game with a specific ruleset they actually enjoy... and as a result they are stuck just constantly upset and bemoaning on places like EN World that the game isn't what they want to play, but they just can't bring themselves to quit playing it. But that ain't our or WotC's problem.
