Given the rather hostile reaction I got to my ideas, I am thinking there is no possible way to fix D&D so that people can play whatever character concept they want and still have a positive experience and contribute meaningfully to the party's success. The whole culture of munchkin min-maxers and those who have a personal favorite character build and expect to be catered to and be superior to the rest of the party is just too strong within the D&D community.
To me, it really seems that if one wants to play a Rogue of any race, use whatever weapon you think exemplifies your character concept, be an acrobat or a suave seductress or a discerning detective or a clever scholar-- your level and class alone is what determines what you roll for attack rolls and damage rolls and for your class specific battle abilities. The race, the theme of your character-- that comes into play when it comes to skill challenges in specific regions and specific situations.
But it seems like there are those who are far too attached to the idea that there should be One True Build and, if you aren't that one build, you need to suck and feel terrible about yourself. There are those who are violently hostile to the idea of people playing characters with green skin and tusks or red skin and cat-like eyes or dark skin at all.
Honestly, I would even be satisfied with the idea that one goes back to a "basic D&D" and an "advanced D&D" where the basic version is for narrative play and you are free to play any sort of character concept you like because the game is super mechanically light and the advanced version caters to those who want to create a munchkin build by finding the loophole the designers accidentally left in the character creation process that allows them to be super powered while the rest of the party can suck it for not abusing rule loopholes and rule lawyering-- and those 50+ year olds who are hostile to anyone playing any character who is not precisely like a character who was a featured protagonist in Lord of the Rings.
But maybe those of us who want a more inclusive game should just create a new RPG and let the Grognards drive the name of Dungeons and Dragons into the grave. Really, I can't help but feel more and more ashamed about the attitudes of so many players who are in the hobbies I enjoyed. It is hard to really understand why what always struck me as the hobbies of the outsiders became the realm of well.... disclusionary people. In the very least, I thought those people peeled off long ago to be funneled into various OSR games.
But maybe what we need is the opposite of an OSR game. I have seen 13th Age and Dungeon World make steps in the right direction, though I cannot say I totally agree with everything they have done. Even Pathfinder 2 seems to be ahead of Dungeons and Dragons in fixing the worst aspects.
I understand that we are all attached to the D&D name and concept but... maybe it is time to let it go. Maybe it is time to let it crash and burn. It was the first, and for that it deserves respect, but by being the first it seems that it attracted and attached to itself far too many people who, after being mistreated by others, desire nothing more than to pass that mistreatment onto other people so as to feel superior. And maybe it is theirs-- they can have it and bring it down with them. And all those 55+-year old people can drag the whole D&D name with them into the sea and drown it as they all die away.
Maybe a new game entirely needs to replace D&D.
Wait, since people were hesitant about making ability scores practically not matter anymore (which I don't feel like I was hostile, more skeptical if anything), you think we're people who want to exclude creativity from the game. I think you should obviously be able to play any race as any class well, but that can be done as simply as removing the racial ability scores from the game.
I just didn't think that making classes no longer be focused on any one ability score made sense, and was too rules-lite. I still think if you want to play a Wizard, you need to be intellectually smart as a character. If a character wants to max out Strength and use that as their ability score to cast Wizard spells, I would immediately say no, because that makes absolutely no sense. I understand this is a fantasy game, but I do personally prefer when things can make sense in my games.
Also, you're saying it's min-maxers who don't like your idea, right? How does that make sense? You idea would promote min-maxing more than anything I've recommended. Suddenly, every person in the game would be a Yuan-Ti Pureblood, maxing Constitution to use it as a spellcasting ability for Druids, Bards, or Clerics.
If you make everyone have the same bonuses to hit and same bonuses for damage, that doesn't promote inclusivity, that diminishes the importance of player choice when they make a character.
I don't want a new game. I like the current game, but would like some possible minor changes in an edition shift. (Also, I am not a grognard. 5e is my first edition of D&D. The entire edition of 3e is older than I am.)
Also, your post was a bit rude. This discussion is meant to be productive and polite. Please continue being so.
