+1 I'd like racial traits to be more impactful
For example, I think making the Underdark lighter just because people who played races without Darkvision complained was a bad move (and people with Darkvision complained that it wasn't working properly). Fix Darkvision and Low-Light Vision instead of making the Underdark a 'sunset'-type place, with reds, purples, and orange hues that every surfacer can see in. And then, if you want to take your party with no Darkvision and no light sources and no light spells in the Underdark, you should deal with the penalties and if you die, you die. Similarly, if you want to roleplay a group of Llolth-Sworn Drow traipsing across the Sword Coast, deal with the penalty for your RP choices.
