What I think D&D should be is a site-exploration, loot-based roguelike with tons of randomization in encounters and character growth opportunities, but with a deep system to create mechanically differentiated, bespoke characters with no starting randomness.
I'm OK with more random character creation in a game with interesting randomized character concepts, along the lines of games like Beyond the Wall, Electric Bastionland, or Troika!. I'm not a fan of "I rolled an 8 Str, and my best stat is 14 Int, so I guess I'll play a wizard."
