Dragonborn should be scrapped and Lizardfolk should be added as a playable race instead.
As an old-school D&D player from decades ago I do feel more comfortable with lizardfolk as a PC race than dragonborn because they better fit my conception of a D&D world. But my conception of the game and its implied setting was formed over four decades ago in a very different cultural context. Today's players are more influenced by anime and manga than Conan or Fafhrd and the Grey Mouser. Their context is different and dragonborn work better in that context than lizardfolk. I don't have to be a fan of dragonborn to recognize that they were the right choice for this game.
