I fully understand it may well be late to offer suggestions or requests at this stage of development, but I have to try. I believe this change would significantly improve BG3 by offering tons of new viable character building options, encourage experimentation and roleplaying.
The Problem Most races grant a predetermined +2/+1 increase to two Ability Scores, with humans, half-elves and mountain dwarves being notable exceptions. This contributes to race being an important character-building choice, but also greatly limits the pool of viable characters. Not starting with a +3 modifier in your primary class ability is a terrible hit to your character's level of power. In Gale's words, "It is to be avoided".
As a result, the narrow selection of race-class combinations where the racial ability increase complements the class completely outshines all other options. We can still have fun with our gnome druids, half-orc wizards and githyanki monks, but we'll be doing so knowing that we're intentionally crippling our characters. This is bad for both character building AND role-playing.
The Solution In Tasha's Cauldron of Everything an optional rule was introduced where starting Ability Score Increases are no longer tied to race. In short, under this new ruling the player assigns bonuses in a +2/+1 or a +1/+1/+1 spread to a combination of Ability Scores determined partly by the player's choice and partly by class, background or both. In the interest of keeping this post short I'll link an article describing the changes (note: this may not be the latest version of the ruling ): https://www.dndbeyond.com/posts/563-reimagining-racial-ability-scores
At first glance it might seem that this ruling simplifies races, removes some of their identity and trivializes getting an optimal Ability spread. In practice it's quite the opposite. It encourages the player to look at each race in terms of the unique features it grants and how it fits the fantasy concept one wants to roleplay rather than just checking if it increases the right number. Dozens of race-class combinations one wouldn't seriously consider before now become viable, which is fantastic for both avid roleplayers and theorycrafting enthusiasts. Everyone wins. It's no surprise that this is now DnD5e's official default ruling for determining Ability Score Increases!
I'm curious to see what the community thinks of this.
