The issue I think Larian are contending with is that even 5e is a complex system. I know this from watching dozens of EA streams of people who aren't DnD familiar getting owned by simple mistakes because they don't understand that Shadowheart's Firebolt uses Intelligence to hit rather than Wisdom for her Guiding Bolt; or that her Mace is a Strength weapon and she is more likely to hit with a dagger. DnD is FULL of traps for inexperienced players to get hardstuck on without a DM to say "that's probably a bad idea".
I feel like introducing a proper tutorial sections and properly tying it to a decent story should do the trick of introducing the game to a new player base. Unfortunately, it becomes impossible when you are from Larian studios and you build your prologue based solely on the rule of cool and then slap a clumsy and messy parody of a tutorial on top of this cool action. I think a proper tutorial and maybe a manual should solve these problems better than scrapping racial ASIs, scrapping multiclass restrictions, letting us respec every 10 minutes and giving fireball to anyone who dipped one time into Wizard.
I don't have your optimism. I would fully expect the zoomer generation of gamers to brute-force through a proper tutorial without understanding it and never open a manual ever. XD
